2023-11-17dm-delay: fix bugs introduced by kthread modeMikulas Patocka1-26/+35
This commit fixes the following bugs introduced by commit 70bbeb29fab0 ("dm delay: for short delays, use kthread instead of timers and wq"): * the function flush_worker_fn has no exit path - on unload, this function will just loop and consume 100% CPU without any progress * the wake-up mechanism in flush_worker_fn is racy - a wake up will be missed if the process adds entries to the delayed_bios list just before set_current_state(TASK_INTERRUPTIBLE) * flush_delayed_bios_fast submits a bio while holding a global mutex; this may deadlock if we have multiple stacked dm-delay devices and the underlying device attempts to acquire the mutex too * if the target constructor fails, it will call delay_dtr. delay_dtr would attempt to free dc->timer_lock without it being initialized by the constructor. * if the target constructor's kthread allocation fails, delay_dtr would crash trying to dereference dc->worker because it is non-NULL due to ERR_PTR.

2023-11-17dm-delay: fix a race between delay_presuspend and delay_bioMikulas Patocka1-5/+11
In delay_presuspend, we set the atomic variable may_delay and then stop the timer and flush pending bios. The intention here is to prevent the delay target from re-arming the timer again. However, this test is racy. Suppose that one thread goes to delay_bio, sees that dc->may_delay is one and proceeds; now, another thread executes delay_presuspend, it sets dc->may_delay to zero, deletes the timer and flushes pending bios. Then, the first thread continues and adds the bio to delayed->list despite the fact that dc->may_delay is false. Fix this bug by changing may_delay's type from atomic_t to bool and only access it while holding the delayed_bios_lock mutex. Note that we don't have to grab the mutex in delay_resume because there are no bios in flight at this point.

2023-11-17platform/x86/amd/pmc: adjust getting DRAM size behaviorShyam Sundar S K1-29/+2
amd_pmc_get_dram_size() is used to get the DRAM size information. But in the current code, mailbox command to get the DRAM size info is sent based on the values of dev->major and dev->minor. But dev->major and dev->minor will have either junk or zero assigned to them until at least once a call to amd_pmc_get_smu_version() is made which ideally populates dev->major and dev->minor. However, adding a amd_pmc_get_smu_version() call to amd_pmc_get_dram_size() has a downside of elevating the boot times. After talking to the PMFW team, it's understood that the "get dram size" mbox command would only be supported on specific platforms (like Mendocino) and not all. So, adjust getting DRAM size behavior such that, - if running on Rembrandt or Mendocino and the underlying PMFW knows how to execute the "get dram size" command it shall give the custom dram size. - if the underlying FW does not report the dram size, we just proceed further and assign the default dram size. The simplest way to address this is to remove amd_pmc_get_dram_size() function and directly call the "get dram size" command in the amd_pmc_s2d_init().

2023-11-17xen: privcmd: Replace zero-length array with flex-array member and use ↵Gustavo A. R. Silva1-1/+1
__counted_by Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct privcmd_kernel_ioreq`. Also annotate array `ports` with `__counted_by()` to prepare for the coming implementation by GCC and Clang of the `__counted_by` attribute. Flexible array members annotated with `__counted_by` can have their accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions). This fixes multiple -Warray-bounds warnings: drivers/xen/privcmd.c:1239:30: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1240:30: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1241:30: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1245:33: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1258:67: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] This results in no differences in binary output.

2023-11-17swiotlb-xen: provide the "max_mapping_size" methodKeith Busch1-0/+1
There's a bug that when using the XEN hypervisor with bios with large multi-page bio vectors on NVMe, the kernel deadlocks [1]. The deadlocks are caused by inability to map a large bio vector - dma_map_sgtable always returns an error, this gets propagated to the block layer as BLK_STS_RESOURCE and the block layer retries the request indefinitely. XEN uses the swiotlb framework to map discontiguous pages into contiguous runs that are submitted to the PCIe device. The swiotlb framework has a limitation on the length of a mapping - this needs to be announced with the max_mapping_size method to make sure that the hardware drivers do not create larger mappings. Without max_mapping_size, the NVMe block driver would create large mappings that overrun the maximum mapping size.

2023-11-17kconfig: fix memory leak from range propertiesMasahiro Yamada1-8/+6
Currently, sym_validate_range() duplicates the range string using xstrdup(), which is overwritten by a subsequent sym_calc_value() call. It results in a memory leak. Instead, only the pointer should be copied. Below is a test case, with a summary from Valgrind. [Test Kconfig] config FOO int "foo" range 10 20 [Test .config] CONFIG_FOO=0 [Before] LEAK SUMMARY: definitely lost: 3 bytes in 1 blocks indirectly lost: 0 bytes in 0 blocks possibly lost: 0 bytes in 0 blocks still reachable: 17,465 bytes in 21 blocks suppressed: 0 bytes in 0 blocks [After] LEAK SUMMARY: definitely lost: 0 bytes in 0 blocks indirectly lost: 0 bytes in 0 blocks possibly lost: 0 bytes in 0 blocks still reachable: 17,462 bytes in 20 blocks suppressed: 0 bytes in 0 blocks Signed-off-by: Masahiro Yamada <[email protected]>

2023-11-17Merge branch 'rxrpc-ack-fixes'David S. Miller2-33/+30
David Howells says: ==================== rxrpc: ACK handling fixes Here are a couple of patches to fix ACK handling in AF_RXRPC: (1) Allow RTT determination to use an ACK of any type as the response from which to calculate RTT, provided ack.serial matches the serial number of the outgoing packet. (2) Defer the response to a PING ACK packet (or any ACK with the REQUEST_ACK flag set) until after we've parsed the packet so that we carry up to date information if the Tx or Rx rings are advanced. ==================== Signed-off-by: David S. Miller <[email protected]>
