2023-06-26f2fs: remove redundant assignment to variable errColin Ian King
The assignment to variable err is redundant since the code jumps to label next and err is then re-assigned a new value on the call to sanity_check_node_chain. Remove the assignment. Cleans up clang scan build warning: fs/f2fs/recovery.c:464:6: warning: Value stored to 'err' is never read [deadcode.DeadStores] Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2023-06-26f2fs: do not issue small discard commands during checkpointJaegeuk Kim
If there're huge # of small discards, this will increase checkpoint latency insanely. Let's issue small discards only by trim. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2023-06-26f2fs: check zone write pointer points to the end of zoneDaeho Jeong

2023-06-26f2fs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO methodChristoph Hellwig
Since commit a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag") file systems can just set the FMODE_CAN_ODIRECT flag at open time instead of wiring up a dummy direct_IO method to indicate support for direct I/O. Do that for f2fs so that noop_direct_IO can eventually be removed. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2023-06-26f2fs: do more sanity check on inodeChao Yu
There are several issues in sanity_check_inode(): - The code looks not clean, it checks extra_attr related condition dispersively. - It missed to check i_extra_isize w/ lower boundary - It missed to check feature dependency: prjquota, inode_chksum, inode_crtime, compression features rely on extra_attr feature. - It's not necessary to check i_extra_isize due to it will only be assigned to non-zero value if f2fs_has_extra_attr() is true in do_read_inode(). Fix them all in this patch. Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

Versal watchdog driver uses window watchdog mode. Window watchdog timer(WWDT) contains closed(first) and open(second) window with 32 bit width. Write to the watchdog timer within predefined window periods of time. This means a period that is not too soon and a period that is not too late. The WWDT has to be restarted within the open window time. If software tries to restart WWDT outside of the open window time period, it generates a reset.

2023-06-26netfilter: conntrack: dccp: copy entire header to stack buffer, not just ↵Florian Westphal
basic one Eric Dumazet says: nf_conntrack_dccp_packet() has an unique: dh = skb_header_pointer(skb, dataoff, sizeof(_dh), &_dh); And nothing more is 'pulled' from the packet, depending on the content. dh->dccph_doff, and/or dh->dccph_x ...) So dccp_ack_seq() is happily reading stuff past the _dh buffer. BUG: KASAN: stack-out-of-bounds in nf_conntrack_dccp_packet+0x1134/0x11c0 Read of size 4 at addr ffff000128f66e0c by task syz-executor.2/29371 [..] Fix this by increasing the stack buffer to also include room for the extra sequence numbers and all the known dccp packet type headers, then pull again after the initial validation of the basic header. While at it, mark packets invalid that lack 48bit sequence bit but where RFC says the type MUST use them. Compile tested only. v2: first skb_header_pointer() now needs to adjust the size to only pull the generic header. (Eric) Heads-up: I intend to remove dccp conntrack support later this year.

2023-06-26lib/ts_bm: reset initial match offset for every block of textJeremy Sowden
The `shift` variable which indicates the offset in the string at which to start matching the pattern is initialized to `bm->patlen - 1`, but it is not reset when a new block is retrieved. This means the implemen- tation may start looking at later and later positions in each successive block and miss occurrences of the pattern at the beginning. E.g., consider a HTTP packet held in a non-linear skb, where the HTTP request line occurs in the second block: [... 52 bytes of packet headers ...] GET /bmtest HTTP/1.1\r\nHost: www.example.com\r\n\r\n and the pattern is "GET /bmtest". Once the first block comprising the packet headers has been examined, `shift` will be pointing to somewhere near the end of the block, and so when the second block is examined the request line at the beginning will be missed. Reinitialize the variable for each new block.

2023-06-26thermal/drivers/stm32: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. st_thermal_unregister() always returned zero, so convert it to return void without any loss and then just drop the return from st_mmap_remove().

Use the new API instead, so the next changes can be pushed in the thermal framework without this driver failing to compile. No functional changes intended.

2023-06-26thermal/drivers/sun8i: Fix some error handling paths in sun8i_ths_probe()Christophe JAILLET
Should an error occur after calling sun8i_ths_resource_init() in the probe function, some resources need to be released, as already done in the .remove() function. Switch to the devm_clk_get_enabled() helper and add a new devm_action to turn sun8i_ths_resource_init() into a fully managed function. Move the place where reset_control_deassert() is called so that the recommended order of reset release/clock enable steps is kept. A64 manual states that: 3.3.6.4. Gating and reset Make sure that the reset signal has been released before the release of module clock gating; This fixes the issue and removes some LoC at the same time.
