2024-07-20Merge tag 'spi-nor/for-6.11' into mtd/nextMiquel Raynal6-302/+89
SPI NOR changes for 6.11 Notable changes: - Drop support for Xilinx S3AN flashes. These flashes are for the very old Xilinx Spartan 3 FPGAs and they need some awkward code in the core to support. Drop support for these flashes, along with the special handling we needed for them in the core like non-power-of-2 page size handling and the .setup() callback. - Fix regression for old w25q128 flashes without SFDP tables. Commit 83e824a4a595 ("mtd: spi-nor: Correct flags for Winbond w25q128") dropped support for such devices under the assumption that they aren't being used anymore. Users have now surfaced [0] so fix the regression by supporting both kind of devices. - Core cleanups including removal of SPI_NOR_NO_FR flag and simplification of spi_nor_get_flash_info().

2024-07-20i2c: piix4: Register SPDsThomas Weißschuh2-0/+10
The piix4 I2C bus can carry SPDs, register them if present. Only look on bus 0, as this is where the SPDs seem to be located. Only the first 8 slots are supported. If the system has more, then these will not be visible. The AUX bus can not be probed as on some platforms it reports all devices present and all reads return "0". This would allow the ee1004 to be probed incorrectly.

2024-07-20Makefile: add comment to discourage tools/* addition for kernel buildsMasahiro Yamada1-0/+6
Kbuild provides scripts/Makefile.host to build host programs used for building the kernel. Unfortunately, there are two exceptions that opt out of Kbuild. The build system under tools/ is a cheesy replica, and cause issues. I was recently poked about a problem in the tools build system, which I do not maintain (and nobody maintains). [1] Without a comment, people might believe this is the right location because that is where objtool lives, even if a more robust Kbuild syntax satisfies their needs.

2024-07-20kconfig: recursive checks drop file/linenoHONG Yifan2-48/+30
This prevents segfault when getting filename and lineno in recursive checks. If the following snippet is found in Kconfig: [Test code 1] config FOO bool depends on BAR select BAR ... without BAR defined; then there is a segfault. Kconfig:34:error: recursive dependency detected! Kconfig:34: symbol FOO depends on BAR make[4]: *** [scripts/kconfig/Makefile:85: allnoconfig] Segmentation fault This is because of the following. BAR is a fake entry created by sym_lookup() with prop being NULL. In the recursive check, there is a NULL check for prop to fall back to stack->sym->prop if stack->prop is NULL. However, in this case, stack->sym points to the fake BAR entry created by sym_lookup(), so prop is still NULL. prop was then referenced without additional NULL checks, causing segfault. As the previous email thread suggests, the file and lineno for select is also wrong: [Test code 2] config FOO bool config BAR bool config FOO bool "FOO" depends on BAR select BAR $ make defconfig *** Default configuration is based on 'x86_64_defconfig' Kconfig:1:error: recursive dependency detected! Kconfig:1: symbol FOO depends on BAR Kconfig:4: symbol BAR is selected by FOO [...] Kconfig:4 should be Kconfig:10.

2024-07-19mailbox: mtk-cmdq: Move devm_mbox_controller_register() after ↵Jason-JH.Lin1-6/+6
devm_pm_runtime_enable() When mtk-cmdq unbinds, a WARN_ON message with condition pm_runtime_get_sync() < 0 occurs. According to the call tracei below: cmdq_mbox_shutdown mbox_free_channel mbox_controller_unregister __devm_mbox_controller_unregister ... The root cause can be deduced to be calling pm_runtime_get_sync() after calling pm_runtime_disable() as observed below: 1. CMDQ driver uses devm_mbox_controller_register() in cmdq_probe() to bind the cmdq device to the mbox_controller, so devm_mbox_controller_unregister() will automatically unregister the device bound to the mailbox controller when the device-managed resource is removed. That means devm_mbox_controller_unregister() and cmdq_mbox_shoutdown() will be called after cmdq_remove(). 2. CMDQ driver also uses devm_pm_runtime_enable() in cmdq_probe() after devm_mbox_controller_register(), so that devm_pm_runtime_disable() will be called after cmdq_remove(), but before devm_mbox_controller_unregister(). To fix this problem, cmdq_probe() needs to move devm_mbox_controller_register() after devm_pm_runtime_enable() to make devm_pm_runtime_disable() be called after devm_mbox_controller_unregister().

The check and warning are very specific to the SPD usage of the i801 driver. That was fine as long as i801 was the only caller of i2c_register_spd(). Now that piix4 will be added as another user of that function, the check and warning are not accurate anymore. Instead of introducing a more complicated calling protocol only to print a warning, drop the warning. Even in cases where not all slots can be probed, then at least probe the 8 slots that can be.

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c fixes from Wolfram Sang: "The I2C core gains documentation updates for the testunit, a cleanup regarding unneeded 'driver_data' and more sanity checks in the char device. For the host drivers, this release includes significant updates, with the primary change being the renaming from "master/slave" to "controller/target" to adhere to I2C v7 and SMBus 3.2 standards. New Support: - Added support for Intel Arrow Lake-H - Added I2C support in the Arioha SoC by linking the Mediatek I2C controller Cleanups: - Added the MODULE_DESCRIPTION() macro, resolving a modpost warning in the ALi 1563 Southbridge driver. - Constified the regmap_config declaration in the i2c-designware driver. - Improved the coding style in the Renesas R-Car driver by removing unnecessary semicolons after brackets. General improvements: - In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with RUNTIME_PM_OPS to enable waking up the controller during suspend() before suspend_noirq() kicks in. - Improved logging in the Xilinx driver. - Added a warning (WARN()) in the Renesas R-Car driver for spurious interrupts. DTS Changes: - Removed address-cell and size-cell from the Atmel at91sam, nVidia Tegra 20, and Samsung S3c2410 devices. - Fixed Texas Instruments OMAP4 I2C controller to comply with the i2c-controller.yaml schema. - Improved indentation in DTS examples for several I2C devices. - Converted the NXP LPC1788 binding to the dt-schema. - Added documentation for the compatible string thead,th1520-i2c. - Added the "power-domains" property for the Meson I2C driver.

We have the usual Qualcomm clk drivers, along with clk drivers for the Sophgo and T-Head vendors, all to support some new SoCs. Nothing in particular stands out to me in the updates. There's the interconnect clk driver which exposes clks as interconnects, crossing subsystems. There's a bunch of janitorial things that are improving drivers in general like kmemdup_array() or fixing error paths.

2024-07-19selftests/vDSO: add tests for vgetrandomJason A. Donenfeld5-0/+351
This adds two tests for vgetrandom. The first one, vdso_test_chacha, simply checks that the assembly implementation of chacha20 matches that of libsodium, a basic sanity check that should catch most errors. The second, vdso_test_getrandom, is a full "libc-like" implementation of the userspace side of vgetrandom() support. It's meant to be used also as example code for libcs that might be integrating this. Cc: [email protected] Signed-off-by: Jason A. Donenfeld <[email protected]>
2024-07-19x86: vdso: Wire up getrandom() vDSO implementationJason A. Donenfeld9-1/+275
Hook up the generic vDSO implementation to the x86 vDSO data page. Since the existing vDSO infrastructure is heavily based on the timekeeping functionality, which works over arrays of bases, a new macro is introduced for vvars that are not arrays. The vDSO function requires a ChaCha20 implementation that does not write to the stack, yet can still do an entire ChaCha20 permutation, so provide this using SSE2, since this is userland code that must work on all x86-64 processors.

2024-07-19random: introduce generic vDSO getrandom() implementationJason A. Donenfeld7-1/+347
Provide a generic C vDSO getrandom() implementation, which operates on an opaque state returned by vgetrandom_alloc() and produces random bytes the same way as getrandom(). This has the following API signature: ssize_t vgetrandom(void *buffer, size_t len, unsigned int flags, void *opaque_state, size_t opaque_len); The return value and the first three arguments are the same as ordinary getrandom(), while the last two arguments are a pointer to the opaque allocated state and its size. Were all five arguments passed to the getrandom() syscall, nothing different would happen, and the functions would have the exact same behavior. The actual vDSO RNG algorithm implemented is the same one implemented by drivers/char/random.c, using the same fast-erasure techniques as that. Should the in-kernel implementation change, so too will the vDSO one. It requires an implementation of ChaCha20 that does not use any stack, in order to maintain forward secrecy if a multi-threaded program forks (though this does not account for a similar issue with SA_SIGINFO copying registers to the stack), so this is left as an architecture-specific fill-in. Stack-less ChaCha20 is an easy algorithm to implement on a variety of architectures, so this shouldn't be too onerous. Initially, the state is keyless, and so the first call makes a getrandom() syscall to generate that key, and then uses it for subsequent calls. By keeping track of a generation counter, it knows when its key is invalidated and it should fetch a new one using the syscall. Later, more than just a generation counter might be used. Since MADV_WIPEONFORK is set on the opaque state, the key and related state is wiped during a fork(), so secrets don't roll over into new processes, and the same state doesn't accidentally generate the same random stream. The generation counter, as well, is always >0, so that the 0 counter is a useful indication of a fork() or otherwise uninitialized state. If the kernel RNG is not yet initialized, then the vDSO always calls the syscall, because that behavior cannot be emulated in userspace, but fortunately that state is short lived and only during early boot. If it has been initialized, then there is no need to inspect the `flags` argument, because the behavior does not change post-initialization regardless of the `flags` value. Since the opaque state passed to it is mutated, vDSO getrandom() is not reentrant, when used with the same opaque state, which libc should be mindful of. The function works over an opaque per-thread state of a particular size, which must be marked VM_WIPEONFORK, VM_DONTDUMP, VM_NORESERVE, and VM_DROPPABLE for proper operation. Over time, the nuances of these allocations may change or grow or even differ based on architectural features. The opaque state passed to vDSO getrandom() must be allocated using the mmap_flags and mmap_prot parameters provided by the vgetrandom_opaque_params struct, which also contains the size of each state. That struct can be obtained with a call to vgetrandom(NULL, 0, 0, &params, ~0UL). Then, libc can call mmap(2) and slice up the returned array into a state per each thread, while ensuring that no single state straddles a page boundary. Libc is expected to allocate a chunk of these on first use, and then dole them out to threads as they're created, allocating more when needed. vDSO getrandom() provides the ability for userspace to generate random bytes quickly and safely, and is intended to be integrated into libc's thread management. As an illustrative example, the introduced code in the vdso_test_getrandom self test later in this series might be used to do the same outside of libc. In a libc the various pthread-isms are expected to be elided into libc internals. Reviewed-by: Thomas Gleixner <[email protected]> Signed-off-by: Jason A. Donenfeld <[email protected]>
2024-07-19mm: add MAP_DROPPABLE for designating always lazily freeable mappingsJason A. Donenfeld17-15/+146
The vDSO getrandom() implementation works with a buffer allocated with a new system call that has certain requirements: - It shouldn't be written to core dumps. * Easy: VM_DONTDUMP. - It should be zeroed on fork. * Easy: VM_WIPEONFORK. - It shouldn't be written to swap. * Uh-oh: mlock is rlimited. * Uh-oh: mlock isn't inherited by forks. - It shouldn't reserve actual memory, but it also shouldn't crash when page faulting in memory if none is available * Uh-oh: VM_NORESERVE means segfaults. It turns out that the vDSO getrandom() function has three really nice characteristics that we can exploit to solve this problem: 1) Due to being wiped during fork(), the vDSO code is already robust to having the contents of the pages it reads zeroed out midway through the function's execution. 2) In the absolute worst case of whatever contingency we're coding for, we have the option to fallback to the getrandom() syscall, and everything is fine. 3) The buffers the function uses are only ever useful for a maximum of 60 seconds -- a sort of cache, rather than a long term allocation. These characteristics mean that we can introduce VM_DROPPABLE, which has the following semantics: a) It never is written out to swap. b) Under memory pressure, mm can just drop the pages (so that they're zero when read back again). c) It is inherited by fork. d) It doesn't count against the mlock budget, since nothing is locked. e) If there's not enough memory to service a page fault, it's not fatal, and no signal is sent. This way, allocations used by vDSO getrandom() can use: VM_DROPPABLE | VM_DONTDUMP | VM_WIPEONFORK | VM_NORESERVE And there will be no problem with OOMing, crashing on overcommitment, using memory when not in use, not wiping on fork(), coredumps, or writing out to swap. In order to let vDSO getrandom() use this, expose these via mmap(2) as MAP_DROPPABLE. Note that this involves removing the MADV_FREE special case from sort_folio(), which according to Yu Zhao is unnecessary and will simply result in an extra call to shrink_folio_list() in the worst case. The chunk removed reenables the swapbacked flag, which we don't want for VM_DROPPABLE, and we can't conditionalize it here because there isn't a vma reference available. Finally, the provided self test ensures that this is working as desired. Cc: [email protected] Acked-by: David Hildenbrand <[email protected]> Signed-off-by: Jason A. Donenfeld <[email protected]>

2024-07-19cifs: Fix setting of zero_point after DIO writeDavid Howells1-5/+10
At the moment, at the end of a DIO write, cifs calls netfs_resize_file() to adjust the size of the file if it needs it. This will reduce the zero_point (the point above which we assume a read will just return zeros) if it's more than the new i_size, but won't increase it. With DIO writes, however, we definitely want to increase it as we have clobbered the local pagecache and then written some data that's not available locally. Fix cifs to make the zero_point above the end of a DIO or unbuffered write. This fixes corruption seen occasionally with the generic/708 xfs-test. In that case, the read-back of some of the written data is being short-circuited and replaced with zeroes.
