Hi Greg, Can you please add these two pstore fixes to 4.14 please? They are prerequisites for another fix I'll be sending to Linus soon that'll be needed in 4.14 (to fix the bug Yaro ran into). b77fa617a2ff ("pstore: Remove needless lock during console writes") ea84b580b955 ("pstore: Convert buf_lock to semaphore") Thanks! -- Kees Cook

[PATCH AUTOSEL 4.9 01/25] iio: adc: xilinx: fix potential use-after-free on remove

by Sasha Levin

From: Sven Van Asbroeck <thesven73(a)gmail.com> [ Upstream commit 62039b6aef63380ba7a37c113bbaeee8a55c5342 ] When cancel_delayed_work() returns, the delayed work may still be running. This means that the core could potentially free the private structure (struct xadc) while the delayed work is still using it. This is a potential use-after-free. Fix by calling cancel_delayed_work_sync(), which waits for any residual work to finish before returning.

[PATCH v5] x86/mm/KASLR: Fix the size of vmemmap section

by Baoquan He

kernel_randomize_memory() hardcodes the size of vmemmap section as 1 TB, to support the maximum amount of system RAM in 4-level paging mode, 64 TB. However, 1 TB is not enough for vmemmap in 5-level paging mode. Assuming the size of struct page is 64 Bytes, to support 4 PB system RAM in 5-level, 64 TB of vmemmap area is needed. The wrong hardcoding may cause vmemmap stamping into the following cpu_entry_area section, if KASLR puts vmemmap very close to cpu_entry_area , and the actual area of vmemmap is much bigger than 1 TB. So here calculate the actual size of vmemmap region, then align up to 1 TB boundary. In 4-level it's always 1 TB. In 5-level it's adjusted on demand. The current code reserves 0.5 PB for vmemmap in 5-level. In this new way, the left space can be saved to join randomization to increase the entropy.

[PATCH, RESEND] RDMA/srp: Accept again source addresses that do not have a port number

by Bart Van Assche

The function srp_parse_in() is used both for parsing source address specifications and for target address specifications. Target addresses must have a port number. Having to specify a port number for source addresses is inconvenient. Make sure that srp_parse_in() supports again parsing addresses with no port number.

[PATCH 2/7] drm/i915/sdvo: Implement proper HDMI audio support for SDVO

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Our SDVO audio support is pretty bogus. We can't push audio over the SDVO bus, so trying to enable audio in the SDVO control register doesn't do anything. In fact it looks like the SDVO encoder will always mix in the audio coming over HDA, and there's no (at least documented) way to disable that from our side. So HDMI audio does work currently but only by luck really. What is missing though is the ELD. To pass the ELD to the audio driver we need to write it to magic buffer in the SDVO encoder hardware which then gets pulled out via HDA in the other end. Ie. pretty much the same thing we had for native HDMI before we started to just pass the ELD between the drivers. This sort of explains why we even have that silly hardware buffer with native HDMI. $ cat /proc/asound/card0/eld#1.0 -monitor_present 0 -eld_valid 0 +monitor_present 1 +eld_valid 1 +monitor_name LG TV +connection_type HDMI +... This also fixes our state readout since we can now query the SDVO encoder about the state of the "ELD valid" and "presence detect" bits. As mentioned those don't actually control whether audio gets sent over the HDMI cable, but it's the best we can do.

[PATCH 1/1] [v4.9.y] coredump: fix race condition between mmget_not_zero()/get_task_mm() and core dumping

by Ajay Kaher

From: Andrea Arcangeli <aarcange(a)redhat.com> commit 1eb719f09f7e319e79f6abf2b9e8c0dcc1c477b5 upstream. The core dumping code has always run without holding the mmap_sem for writing, despite that is the only way to ensure that the entire vma layout will not change from under it. Only using some signal serialization on the processes belonging to the mm is not nearly enough. This was pointed out earlier. For example in Hugh's post from Jul 2017: https://lkml.kernel.org/r/alpine.LSU.2.11.1707191716030.2055@eggly.anvils "Not strictly relevant here, but a related note: I was very surprised to discover, only quite recently, how handle_mm_fault() may be called without down_read(mmap_sem) - when core dumping. That seems a misguided optimization to me, which would also be nice to correct" In particular because the growsdown and growsup can move the vm_start/vm_end the various loops the core dump does around the vma will not be consistent if page faults can happen concurrently. Pretty much all users calling mmget_not_zero()/get_task_mm() and then taking the mmap_sem had the potential to introduce unexpected side effects in the core dumping code. Adding mmap_sem for writing around the ->core_dump invocation is a viable long term fix, but it requires removing all copy user and page faults and to replace them with get_dump_page() for all binary formats which is not suitable as a short term fix. For the time being this solution manually covers the places that can confuse the core dump either by altering the vma layout or the vma flags while it runs. Once ->core_dump runs under mmap_sem for writing the function mmget_still_valid() can be dropped. Allowing mmap_sem protected sections to run in parallel with the coredump provides some minor parallelism advantage to the swapoff code (which seems to be safe enough by never mangling any vma field and can keep doing swapins in parallel to the core dumping) and to some other corner case. In order to facilitate the backporting I added "Fixes: 86039bd3b4e6" however the side effect of this same race condition in /proc/pid/mem should be reproducible since before 2.6.12-rc2 so I couldn't add any other "Fixes:" because there's no hash beyond the git genesis commit. Because find_extend_vma() is the only location outside of the process context that could modify the "mm" structures under mmap_sem for reading, by adding the mmget_still_valid() check to it, all other cases that take the mmap_sem for reading don't need the new check after mmget_not_zero()/get_task_mm(). The expand_stack() in page fault context also doesn't need the new check, because all tasks under core dumping are frozen.

[PATCH] usb: dwc2: host: Fix wMaxPacketSize handling (fix webcam regression)

by Douglas Anderson

In commit abb621844f6a ("usb: ch9: make usb_endpoint_maxp() return only packet size") the API to usb_endpoint_maxp() changed. It used to just return wMaxPacketSize but after that commit it returned wMaxPacketSize with the high bits (the multiplier) masked off. If you wanted to get the multiplier it was now up to your code to call the new usb_endpoint_maxp_mult() which was introduced in commit 541b6fe63023 ("usb: add helper to extract bits 12:11 of wMaxPacketSize"). Prior to the API change most host drivers were updated, but no update was made to dwc2. Presumably it was assumed that dwc2 was too simplistic to use the multiplier and thus just didn't support a certain class of USB devices. However, it turns out that dwc2 did use the multiplier and many devices using it were working quite nicely. That means that many USB devices have been broken since the API change. One such device is a Logitech HD Pro Webcam C920. Specifically, though dwc2 didn't directly call usb_endpoint_maxp(), it did call usb_maxpacket() which in turn called usb_endpoint_maxp(). Let's update dwc2 to work properly with the new API.

[PATCH] crypto: chacha20poly1305 - fix atomic sleep when using async algorithm

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Clear the CRYPTO_TFM_REQ_MAY_SLEEP flag when the chacha20poly1305 operation is being continued from an async completion callback, since sleeping may not be allowed in that context. This is basically the same bug that was recently fixed in the xts and lrw templates. But, it's always been broken in chacha20poly1305 too. This was found using syzkaller in combination with the updated crypto self-tests which actually test the MAY_SLEEP flag now. Reproducer: python -c 'import socket; socket.socket(socket.AF_ALG, 5, 0).bind( ("aead", "rfc7539(cryptd(chacha20-generic),poly1305-generic)"))' Kernel output: BUG: sleeping function called from invalid context at include/crypto/algapi.h:426 in_atomic(): 1, irqs_disabled(): 0, pid: 1001, name: kworker/2:2 [...] CPU: 2 PID: 1001 Comm: kworker/2:2 Not tainted 5.2.0-rc2 #5 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-20181126_142135-anatol 04/01/2014 Workqueue: crypto cryptd_queue_worker Call Trace: __dump_stack lib/dump_stack.c:77 [inline] dump_stack+0x4d/0x6a lib/dump_stack.c:113 ___might_sleep kernel/sched/core.c:6138 [inline] ___might_sleep.cold.19+0x8e/0x9f kernel/sched/core.c:6095 crypto_yield include/crypto/algapi.h:426 [inline] crypto_hash_walk_done+0xd6/0x100 crypto/ahash.c:113 shash_ahash_update+0x41/0x60 crypto/shash.c:251 shash_async_update+0xd/0x10 crypto/shash.c:260 crypto_ahash_update include/crypto/hash.h:539 [inline] poly_setkey+0xf6/0x130 crypto/chacha20poly1305.c:337 poly_init+0x51/0x60 crypto/chacha20poly1305.c:364 async_done_continue crypto/chacha20poly1305.c:78 [inline] poly_genkey_done+0x15/0x30 crypto/chacha20poly1305.c:369 cryptd_skcipher_complete+0x29/0x70 crypto/cryptd.c:279 cryptd_skcipher_decrypt+0xcd/0x110 crypto/cryptd.c:339 cryptd_queue_worker+0x70/0xa0 crypto/cryptd.c:184 process_one_work+0x1ed/0x420 kernel/workqueue.c:2269 worker_thread+0x3e/0x3a0 kernel/workqueue.c:2415 kthread+0x11f/0x140 kernel/kthread.c:255 ret_from_fork+0x1f/0x30 arch/x86/entry/entry_64.S:352 Fixes: 71ebc4d1b27d ("crypto: chacha20poly1305 - Add a ChaCha20-Poly1305 AEAD construction, RFC7539") Cc: <stable(a)vger.kernel.org> # v4.2+ Cc: Martin Willi <martin(a)strongswan.org> Signed-off-by: Eric Biggers <ebiggers(a)google.com> --- crypto/chacha20poly1305.c | 30 +++++++++++++++++++----------- 1 file changed, 19 insertions(+), 11 deletions(-) diff --git a/crypto/chacha20poly1305.c b/crypto/chacha20poly1305.c index e38a2d61819a7..acbbf010222e3 100644 --- a/crypto/chacha20poly1305.c +++ b/crypto/chacha20poly1305.c @@ -65,6 +65,8 @@ struct chachapoly_req_ctx { unsigned int cryptlen;
