[Public] Hi, Newer GPU microcode binaries for products with DCN 314 cause the display to fail to resume from s2idle. The following fix went into 6.3 that makes it work with both newer and older GPU microcode binaries. Please take this to 6.1.y. e383b12709e32 ("drm/amd/display: Move DCN314 DOMAIN power control to DMCUB") Thanks,

USB4 DPIA fixups for 6.1.y/6.2

by Limonciello, Mario

Hi, The following two commits help with initialization of DPIA which is used for DP tunneling over USB4 within amdgpu. Needed for both 6.1.y and 6.2.y: ead08b95fa50 ("drm/amd/display: Fix race condition in DPIA AUX transfer") 0cf8307adbc6 ("drm/amd/display: Properly reuse completion structure") Needed just for 6.2: 0cf8307adbc6 ("drm/amd/display: Properly reuse completion structure") 0cf8307adbc6 was actually already tagged to go stable but it doesn’t apply cleanly to 6.1.y because of the above mentioned dependency so it didn’t come back. Can you please bring them back as requested above? Thanks,

[PATCH 5.10] md: Flush workqueue md_rdev_misc_wq in md_alloc()

by Hou Tao

From: David Sloan <david.sloan(a)eideticom.com> commit 5e8daf906f890560df430d30617c692a794acb73 upstream. A race condition still exists when removing and re-creating md devices in test cases. However, it is only seen on some setups. The race condition was tracked down to a reference still being held to the kobject by the rdev in the md_rdev_misc_wq which will be released in rdev_delayed_delete(). md_alloc() waits for previous deletions by waiting on the md_misc_wq, but the md_rdev_misc_wq may still be holding a reference to a recently removed device. To fix this, also flush the md_rdev_misc_wq in md_alloc().

Please backport commit ae3419fbac84 ("vc_screen: don't clobber return value in vcs_read")

by Thomas Weißschuh

Hi, please backport the following commit[0] to all stable releases that contain the commit 226fae124b2d ("vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF") Commit 46d733d0efc7 ("vc_screen: modify vcs_size() handling in vcs_read()") [1] also tries to fix this commit but should not actually be necessary for a proper fix. It may make sense to also backport for consistency. commit ae3419fbac845b4d3f3a9fae4cc80c68d82cdf6e Author: Thomas Weißschuh <linux(a)weissschuh.net> Date: Mon Feb 20 06:46:12 2023 +0000 vc_screen: don't clobber return value in vcs_read Commit 226fae124b2d ("vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF") moved the call to vcs_vc() into the loop. While doing this it also moved the unconditional assignment of ret = -ENXIO; This unconditional assignment was valid outside the loop but within it it clobbers the actual value of ret. To avoid this only assign "ret = -ENXIO" when actually needed.

stable/6.2: backport commit 943f4e64ee17 ("ALSA: hda: cs35l41: Correct error condition handling")

by Richard Fitzgerald

commit 943f4e64ee177cf44d7f2c235281fcda7c32bb28 upstream Please backport to 6.2. This fixes an API break between the cs_dsp driver and the cs35l41 HDA driver that broke the cs35l41 driver. The original chain of patches that made the cs_dsp change missed out the corresponding change to the HDA code. These changes went into the first 6.2 release.

Ahoj

by silverl ynrojas

drahý příteli Jak se dneska máš? Myslím, že už je to dlouho, co jsme spolu mluvili naposledy. V každém případě Vás budu znovu kontaktovat ohledně naší předchozí transakce, která u Vás nebyla úspěšná. Vaše spolupráce se mnou bohužel nemůže dokončit převod finančních prostředků. Nevím, možná proto, že se musím smířit se svým zájmem o případ. V každém případě jsem rád, že mohu oznámit úspěch při přijímání finančních prostředků převedených novým partnerem z Venezuely. Momentálně jsem ve Venezuele kvůli investici. Nezapomněl jsem však na své předchozí snažení a snažil jsem se mi s převodem fondu pomoci, i když jsme nemohli dojít ke konkrétnímu závěru. Díky mé snaze pomoci mně jsme se s mým novým partnerem rozhodli vrátit vám 850 000 $, abyste si s námi mohli užívat radosti a štěstí. Nechal jsem vaše kompenzační vízum pro svou sekretářku, aby mi pomohla podat žádost. Nyní kontaktujte mou sekretářku v Togu, jmenuje se paní Silverly Rojas a její e-mailová adresa je (silverlynrojas94(a)gmail.com). Řekněte jí, aby vám poslala kartu Visa v hodnotě 850 000 USD. V současné době jsem velmi zaneprázdněn ve Venezuele kvůli investičním projektům, které mám se svým novým partnerem. Rychle kontaktujte paní Silverly Rojasovou a dejte jí vědět, kam má poslat čekající vízum. Karta vám bude obratem zaslána. Přeji vám vše nejlepší ve všech vašich snahách. S pozdravem Robert G Mohammed

[PATCH 1/3] usb: ucsi: Fix NULL pointer deref in ucsi_connector_change()

by Hans de Goede

When ucsi_init() fails, ucsi->connector is NULL, yet in case of ucsi_acpi we may still get events which cause the ucs_acpi code to call ucsi_connector_change(), which then derefs the NULL ucsi->connector pointer. Fix this by adding a check for ucsi->connector being NULL, as is already done in ucsi_resume() for similar reasons.
