2022-04-19ALSA: hda/i915: Fix one too many pci_dev_put()Lucas De Marchi
pci_get_class() will already unref the pci device passed as argument. So if it's unconditionally unref'ed, even if the loop is not stopped, there will be one too many unref for each device not matched. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5701 Fixes: c9db8a30d9f0 ("ALSA: hda/i915 - skip acomp init if no matching display") Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Link: https://lore.kernel.org/r/20220416064418.2364582-1-lucas.demarchi@intel.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
2022-04-18scsi: sr: Do not leak information in ioctlTom Rix
sr_ioctl.c uses this pattern: result = sr_do_ioctl(cd, &cgc); to-user = buffer[]; kfree(buffer); return result; Use of a buffer without checking leaks information. Check result and jump over the use of buffer if there is an error. result = sr_do_ioctl(cd, &cgc); if (result) goto err; to-user = buffer[]; err: kfree(buffer); return result; Additionally, initialize the buffer to zero. This problem can be seen in the 2.4.0 kernel.

This patch reverts commit 7082a29c22ac ("ARC: use ACCESS_ONCE in cmpxchg loop"). It is not necessary to use READ_ONCE() because cmpxchg contains barrier.

2022-04-18net: atlantic: invert deep par in pm functions, preventing null derefsManuel Ullmann
This will reset deeply on freeze and thaw instead of suspend and resume and prevent null pointer dereferences of the uninitialized ring 0 buffer while thawing. The impact is an indefinitely hanging kernel. You can't switch consoles after this and the only possible user interaction is SysRq. BUG: kernel NULL pointer dereference RIP: 0010:aq_ring_rx_fill+0xcf/0x210 [atlantic] aq_vec_init+0x85/0xe0 [atlantic] aq_nic_init+0xf7/0x1d0 [atlantic] atl_resume_common+0x4f/0x100 [atlantic] pci_pm_thaw+0x42/0xa0 resolves in aq_ring.o to ``` 0000000000000ae0 <aq_ring_rx_fill>: { /* ... */ baf: 48 8b 43 08 mov 0x8(%rbx),%rax buff->flags = 0U; /* buff is NULL */ ``` The bug has been present since the introduction of the new pm code in 8aaa112a57c1 ("net: atlantic: refactoring pm logic") and was hidden until 8ce84271697a ("net: atlantic: changes for multi-TC support"), which refactored the aq_vec_{free,alloc} functions into aq_vec_{,ring}_{free,alloc}, but is technically not wrong. The original functions just always reinitialized the buffers on S3/S4. If the interface is down before freezing, the bug does not occur. It does not matter, whether the initrd contains and loads the module before thawing. So the fix is to invert the boolean parameter deep in all pm function calls, which was clearly intended to be set like that. First report was on Github [1], which you have to guess from the resume logs in the posted dmesg snippet. Recently I posted one on Bugzilla [2], since I did not have an AQC device so far. #regzbot introduced: 8ce84271697a #regzbot from: koo5 <kolman.jindrich@gmail.com> #regzbot monitor: https://github.com/Aquantia/AQtion/issues/32 Fixes: 8aaa112a57c1 ("net: atlantic: refactoring pm logic") Link: https://github.com/Aquantia/AQtion/issues/32 [1] Link: https://bugzilla.kernel.org/show_bug.cgi?id=215798 [2] Cc: stable@vger.kernel.org Reported-by: koo5 <kolman.jindrich@gmail.com> Signed-off-by: Manuel Ullmann <labre@posteo.de> Signed-off-by: David S.

2022-04-17can: isotp: stop timeout monitoring when no first frame was sentOliver Hartkopp
The first attempt to fix a the 'impossible' WARN_ON_ONCE(1) in isotp_tx_timer_handler() focussed on the identical CAN IDs created by the syzbot reproducer and lead to upstream fix/commit 3ea566422cbd ("can: isotp: sanitize CAN ID checks in isotp_bind()"). But this did not catch the root cause of the wrong tx.state in the tx_timer handler. In the isotp 'first frame' case a timeout monitoring needs to be started before the 'first frame' is send. But when this sending failed the timeout monitoring for this specific frame has to be disabled too. Otherwise the tx_timer is fired with the 'warn me' tx.state of ISOTP_IDLE.

Move @nr_events increment before REQ_F_CQE_SKIP check. We'll potentially return the value greater than the real one, but iopolling will deal with it and the userspace will re-iopoll if needed.

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator fixes from Jason Donenfeld: - Per your suggestion, random reads now won't fail if there's a page fault after some non-zero amount of data has been read, which makes the behavior consistent with all other reads in the kernel. - Rather than an inconsistent mix of random_get_entropy() returning an unsigned long or a cycles_t, now it just returns an unsigned long. - A memcpy() was replaced with an memmove(), because the addresses are sometimes overlapping. In practice the destination is always before the source, so not really an issue, but better to be correct than not. * tag 'random-5.18-rc3-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: use memmove instead of memcpy for remaining 32 bytes random: make random_get_entropy() return an unsigned long random: allow partial reads if later user copies fail
