2022-08-25ionic: fix up issues with handling EAGAIN on FW cmdsShannon Nelson1-1/+3
In looping on FW update tests we occasionally see the FW_ACTIVATE_STATUS command fail while it is in its EAGAIN loop waiting for the FW activate step to finsh inside the FW. The firmware is complaining that the done bit is set when a new dev_cmd is going to be processed. Doing a clean on the cmd registers and doorbell before exiting the wait-for-done and cleaning the done bit before the sleep prevents this from occurring.

2022-08-25ionic: clear broken state on generation changeShannon Nelson1-0/+3
There is a case found in heavy testing where a link flap happens just before a firmware Recovery event and the driver gets stuck in the BROKEN state. This comes from the driver getting interrupted by a FW generation change when coming back up from the link flap, and the call to ionic_start_queues() in ionic_link_status_check() fails. This can be addressed by having the fw_up code clear the BROKEN bit if seen, rather than waiting for a user to manually force the interface down and then back up.

2022-08-25rxrpc: Fix locking in rxrpc's sendmsgDavid Howells2-39/+57
Fix three bugs in the rxrpc's sendmsg implementation: (1) rxrpc_new_client_call() should release the socket lock when returning an error from rxrpc_get_call_slot(). (2) rxrpc_wait_for_tx_window_intr() will return without the call mutex held in the event that we're interrupted by a signal whilst waiting for tx space on the socket or relocking the call mutex afterwards. Fix this by: (a) moving the unlock/lock of the call mutex up to rxrpc_send_data() such that the lock is not held around all of rxrpc_wait_for_tx_window*() and (b) indicating to higher callers whether we're return with the lock dropped. Note that this means recvmsg() will not block on this call whilst we're waiting. (3) After dropping and regaining the call mutex, rxrpc_send_data() needs to go and recheck the state of the tx_pending buffer and the tx_total_len check in case we raced with another sendmsg() on the same call. Thinking on this some more, it might make sense to have different locks for sendmsg() and recvmsg(). There's probably no need to make recvmsg() wait for sendmsg(). It does mean that recvmsg() can return MSG_EOR indicating that a call is dead before a sendmsg() to that call returns - but that can currently happen anyway. Without fix (2), something like the following can be induced: WARNING: bad unlock balance detected! 5.16.0-rc6-syzkaller #0 Not tainted ------------------------------------- syz-executor011/3597 is trying to release lock (&call->user_mutex) at: [<ffffffff885163a3>] rxrpc_do_sendmsg+0xc13/0x1350 net/rxrpc/sendmsg.c:748 but there are no more locks to release! other info that might help us debug this: no locks held by syz-executor011/3597. ...

2022-08-25xen/privcmd: fix error exit of privcmd_ioctl_dm_op()Juergen Gross1-10/+11
The error exit of privcmd_ioctl_dm_op() is calling unlock_pages() potentially with pages being NULL, leading to a NULL dereference. Additionally lock_pages() doesn't check for pin_user_pages_fast() having been completely successful, resulting in potentially not locking all pages into memory. This could result in sporadic failures when using the related memory in user mode. Fix all of that by calling unlock_pages() always with the real number of pinned pages, which will be zero in case pages being NULL, and by checking the number of pages pinned by pin_user_pages_fast() matching the expected number of pages.

2022-08-25s390/mm: do not trigger write fault when vma does not allow VM_WRITEGerald Schaefer1-1/+3
For non-protection pXd_none() page faults in do_dat_exception(), we call do_exception() with access == (VM_READ | VM_WRITE | VM_EXEC). In do_exception(), vma->vm_flags is checked against that before calling handle_mm_fault(). Since commit 92f842eac7ee3 ("[S390] store indication fault optimization"), we call handle_mm_fault() with FAULT_FLAG_WRITE, when recognizing that it was a write access. However, the vma flags check is still only checking against (VM_READ | VM_WRITE | VM_EXEC), and therefore also calling handle_mm_fault() with FAULT_FLAG_WRITE in cases where the vma does not allow VM_WRITE. Fix this by changing access check in do_exception() to VM_WRITE only, when recognizing write access.

2022-08-25s390: fix double free of GS and RI CBs on fork() failureBrian Foster1-6/+16
The pointers for guarded storage and runtime instrumentation control blocks are stored in the thread_struct of the associated task. These pointers are initially copied on fork() via arch_dup_task_struct() and then cleared via copy_thread() before fork() returns. If fork() happens to fail after the initial task dup and before copy_thread(), the newly allocated task and associated thread_struct memory are freed via free_task() -> arch_release_task_struct(). This results in a double free of the guarded storage and runtime info structs because the fields in the failed task still refer to memory associated with the source task. This problem can manifest as a BUG_ON() in set_freepointer() (with CONFIG_SLAB_FREELIST_HARDENED enabled) or KASAN splat (if enabled) when running trinity syscall fuzz tests on s390x. To avoid this problem, clear the associated pointer fields in arch_dup_task_struct() immediately after the new task is copied. Note that the RI flag is still cleared in copy_thread() because it resides in thread stack memory and that is where stack info is copied.

LoongArch only support 32-bit/64-bit xchg/cmpxchg in native. But percpu operation, qspinlock and some drivers need 8-bit/16-bit xchg/cmpxchg. We add subword xchg/cmpxchg emulation in this patch because the emulation has better performance than the generic implementation (on NUMA system), and it can fix some build errors meanwhile [1]. LoongArch's guarantee for forward progress (avoid many ll/sc happening at the same time and no one succeeds): We have the "exclusive access (with timeout) of ll" feature to avoid simultaneous ll (which also blocks other memory load/store on the same address), and the "random delay of sc" feature to avoid simultaneous sc. It is a mandatory requirement for multi-core LoongArch processors to implement such features, only except those single-core and dual-core processors (they also don't support multi-chip interconnection). Feature bits are introduced in CPUCFG3, bit 3 and bit 4 [2].

Instead report EINVAl. 7) Enable chain stats update via static key iff no error occurs. 8) Restrict osf expression to ip, ip6 and inet families. 9) Restrict tunnel expression to netdev family. 10) Fix crash when trying to bind again an already bound chain. 11) Flowtable garbage collector might leave behind pending work to delete entries. This patch comes with a previous preparation patch as dependency. 12) Allow net.netfilter.nf_conntrack_frag6_high_thresh to be lowered, from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_defrag_ipv6: allow nf_conntrack_frag6_high_thresh increases netfilter: flowtable: fix stuck flows on cleanup due to pending work netfilter: flowtable: add function to invoke garbage collection immediately netfilter: nf_tables: disallow binding to already bound chain netfilter: nft_tunnel: restrict it to netdev family netfilter: nft_osf: restrict osf to ipv4, ipv6 and inet families netfilter: nf_tables: do not leave chain stats enabled on error netfilter: nft_payload: do not truncate csum_offset and csum_type netfilter: nft_payload: report ERANGE for too long offset and length netfilter: nf_tables: make table handle allocation per-netns friendly netfilter: nf_tables: disallow updates of implicit chain netfilter: nft_tproxy: restrict to prerouting hook netfilter: conntrack: work around exceeded receive window netfilter: ebtables: reject blobs that don't provide all entry points ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2022-08-24fbdev: fb_pm2fb: Avoid potential divide by zero errorLetu Ren1-0/+5
In `do_fb_ioctl()` of fbmem.c, if cmd is FBIOPUT_VSCREENINFO, var will be copied from user, then go through `fb_set_var()` and `info->fbops->fb_check_var()` which could may be `pm2fb_check_var()`. Along the path, `var->pixclock` won't be modified. This function checks whether reciprocal of `var->pixclock` is too high. If `var->pixclock` is zero, there will be a divide by zero error. So, it is necessary to check whether denominator is zero to avoid crash. As this bug is found by Syzkaller, logs are listed below. divide error in pm2fb_check_var Call Trace: <TASK> fb_set_var+0x367/0xeb0 drivers/video/fbdev/core/fbmem.c:1015 do_fb_ioctl+0x234/0x670 drivers/video/fbdev/core/fbmem.c:1110 fb_ioctl+0xdd/0x130 drivers/video/fbdev/core/fbmem.c:1189 Reported-by: Zheyu Ma <[email protected]> Signed-off-by: Letu Ren <[email protected]> Signed-off-by: Helge Deller <[email protected]>

It was not possible to create 1-tuple flow director rule for IPv6 flow type. It was caused by incorrectly checking for source IP address when validating user provided destination IP address. Fix this by changing ip6src to correct ip6dst address in destination IP address validation for IPv6 flow type.

2022-08-24ixgbe: stop resetting SYSTIME in ixgbe_ptp_start_cyclecounterJacob Keller1-13/+46
The ixgbe_ptp_start_cyclecounter is intended to be called whenever the cyclecounter parameters need to be changed. Since commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x devices"), this function has cleared the SYSTIME registers and reset the TSAUXC DISABLE_SYSTIME bit. While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear them during ixgbe_ptp_start_cyclecounter. This function may be called during both reset and link status change. When link changes, the SYSTIME counter is still operating normally, but the cyclecounter should be updated to account for the possibly changed parameters. Clearing SYSTIME when link changes causes the timecounter to jump because the cycle counter now reads zero. Extract the SYSTIME initialization out to a new function and call this during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids an unnecessary reset of the current time. This also restores the original SYSTIME clearing that occurred during ixgbe_ptp_reset before the commit above.
