2024-05-20regulator: tps6287x: Force writing VSEL bitMatti Vaittinen
The data-sheet for TPS6287x-Q1 https://www.ti.com/lit/ds/symlink/tps62873-q1.pdf states at chapter 9.3.6.1 Output Voltage Range: "Note that every change to the VRANGE[1:0] bits must be followed by a write to the VSET register, even if the value of the VSET[7:0] bits does not change." The current implementation of the driver uses the regulator_set_voltage_sel_pickable_regmap() helper which further uses regmap_update_bits() to write the VSET-register. The regmap_update_bits() will not access the hardware if the new register value is same as old. It is worth noting that this is true also when the register is marked volatile, which I can't say is wrong because 'read-mnodify-write'-cycle with a volatile register is in any case something user should carefully consider. The 'range_applied_by_vsel'-flag in regulator desc was added to force the vsel register upodates by using regmap_write_bits(). This variant will always unconditionally write the bits to the hardware. It is worth noting that the vsel is now forced to be written to the hardware, whether the range was changed or not. This may cause a performance drop if users are wrtiting same voltage value repeteadly. It would be possible to read the range register to determine if it was changed, but this would be a performance issue for users who don't use reg cache for vsel. Always write the VSET register to the hardware regardless the cache.

2024-05-21erofs: avoid allocating DEFLATE streams before mountingGao Xiang
Currently, each DEFLATE stream takes one 32 KiB permanent internal window buffer even if there is no running instance which uses DEFLATE algorithm. It's unexpected and wasteful on embedded devices with limited resources and servers with hundreds of CPU cores if DEFLATE is enabled but unused.

2024-05-20regulator: pickable ranges: don't always cache vselMatti Vaittinen
Some PMICs treat the vsel_reg same as apply-bit. Eg, when voltage range is changed, the new voltage setting is not taking effect until the vsel register is written. Add a flag 'range_applied_by_vsel' to the regulator desc to indicate this behaviour and to force the vsel value to be written to hardware if range was changed, even if the old selector was same as the new one.

Under the scenario of IB device bonding, when bringing down one of the ports, or all ports, we saw xprtrdma entering a non-recoverable state where it is not even possible to complete the disconnect and shut it down the mount, requiring a reboot. Following debug, we saw that transport connect never ended after receiving the RDMA_CM_EVENT_DEVICE_REMOVAL callback. The DEVICE_REMOVAL callback is irrespective of whether the CM_ID is connected, and ESTABLISHED may not have happened. So need to work with each of these states accordingly.

Olga showed me a case where the client was sending multiple READ_PLUS calls to the server in parallel, and the server replied NFS4ERR_OPNOTSUPP to each. The client would fall back to READ for the first reply, but fail to retry the other calls. I fix this by removing the test for NFS_CAP_READ_PLUS in nfs4_read_plus_not_supported().

2024-05-20sunrpc: fix NFSACL RPC retry on soft mountDan Aloni
It used to be quite awhile ago since 1b63a75180c6 ('SUNRPC: Refactor rpc_clone_client()'), in 2012, that `cl_timeout` was copied in so that all mount parameters propagate to NFSACL clients. However since that change, if mount options as follows are given: soft,timeo=50,retrans=16,vers=3 The resultant NFSACL client receives: cl_softrtry: 1 cl_timeout: to_initval=60000, to_maxval=60000, to_increment=0, to_retries=2, to_exponential=0 These values lead to NFSACL operations not being retried under the condition of transient network outages with soft mount. Instead, getacl call fails after 60 seconds with EIO. The simple fix is to pass the existing client's `cl_timeout` as the new client timeout.

2024-05-20SUNRPC: fix handling expired GSS contextOlga Kornievskaia
In the case where we have received a successful reply to an RPC request, but while processing the reply the client in rpc_decode_header() finds an expired context, the code ends up propagating the error to the caller instead of getting a new context and retrying the request. To give more details, in rpc_decode_header() we call rpcauth_checkverf() will call into the gss and internally will at some point call gss_validate() which has a check if the current’s context lifetime expired, and it would fail. The reason for the failure gets ‘scrubbed’ and translated to EACCES so when we get back to rpc_decode_header() we just go to “out_verifier” which for that error would get converted to “out_garbage” (ie it’s treated as garballed reply) and the next action is call_encode. Which (1) doesn’t reencode or re-send (not to mention no upcall happens because context expires as that reason just not known) and it again fails in the same decoding process. After re-trying it 3 times the error is propagated back to the caller (ie nfs4_write_done_cb() in the case a failing write). To fix this, instead we need to look to the case where the server decides that context has expired and replies with an RPC auth error. In that case, the rpc_decode_header() goes to "out_msg_denied" in that we return EKEYREJECTED which in call_decode() is sent to “call_reserve” which triggers an upcalls and a re-try of the operation. The proposed fix is in case of a failed rpc_decode_header() to check if credentials were set to be invalid and use that as a proxy for deciding that context has expired and then treat is same way as receiving an auth error.

2024-05-20NFS: add atomic_open for NFSv3 to handle O_TRUNC correctly.NeilBrown
With two clients, each with NFSv3 mounts of the same directory, the sequence: client1 client2 ls -l afile echo hello there > afile echo HELLO > afile cat afile will show HELLO there because the O_TRUNC requested in the final 'echo' doesn't take effect. This is because the "Negative dentry, just create a file" section in lookup_open() assumes that the file *does* get created since the dentry was negative, so it sets FMODE_CREATED, and this causes do_open() to clear O_TRUNC and so the file doesn't get truncated. Even mounting with -o lookupcache=none does not help as nfs_neg_need_reval() always returns false if LOOKUP_CREATE is set. This patch fixes the problem by providing an atomic_open inode operation for NFSv3 (and v2). The code is largely the code from the branch in lookup_open() when atomic_open is not provided. The significant change is that the O_TRUNC flag is passed a new nfs_do_create() which add 'trunc' handling to nfs_create(). With this change we also optimise away an unnecessary LOOKUP before the file is created. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

The seg6_input() function is responsible for adding the SRH into a packet, delegating the operation to the seg6_input_core(). This function uses the skb_cow_head() to ensure that there is sufficient headroom in the sk_buff for accommodating the link-layer header. In the event that the skb_cow_header() function fails, the seg6_input_core() catches the error but it does not release the sk_buff, which will result in a memory leak. This issue was introduced in commit af3b5158b89d ("ipv6: sr: fix BUG due to headroom too small after SRH push") and persists even after commit 7a3f5b0de364 ("netfilter: add netfilter hooks to SRv6 data plane"), where the entire seg6_input() code was refactored to deal with netfilter hooks. The proposed patch addresses the identified memory leak by requiring the seg6_input_core() function to release the sk_buff in the event that skb_cow_head() fails.

2024-05-20net: Always descend into dsa/ folder with CONFIG_NET_DSA enabledFlorian Fainelli
Stephen reported that he was unable to get the dsa_loop driver to get probed, and the reason ended up being because he had CONFIG_FIXED_PHY=y in his kernel configuration. As Masahiro explained it: "obj-m += dsa/" means everything under dsa/ must be modular. If there is a built-in object under dsa/ with CONFIG_NET_DSA=m, you cannot do "obj-$(CONFIG_NET_DSA) += dsa/". You need to change it back to "obj-y += dsa/". This was the case here whereby CONFIG_NET_DSA=m, and so the obj-$(CONFIG_FIXED_PHY) += dsa_loop_bdinfo.o rule is not executed and the DSA loop mdio_board info structure is not registered with the kernel, and eventually the device is simply not found. To preserve the intention of the original commit of limiting the amount of folder descending, conditionally descend into drivers/net/dsa when CONFIG_NET_DSA is enabled.

2024-05-20bcachefs: bch2_checksum() returns 0 for unknown checksum typeKent Overstreet
This fixes missing guards on trying to calculate a checksum with an invalid/unknown checksum type; moving the guards up to e.g. btree_io.c might be "more correct", but doesn't buy us anything - an unknown checksum type will always be flagged as at least a checksum error so we aren't losing any safety doing it this way and it makes it less likely to accidentally pop an assert we don't want.

2024-05-20bcachefs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO methodYouling Tang
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 bcachefs so that noop_direct_IO can eventually be removed. Similar to commit b29434999371 ("xfs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO method").

It took me some time to understand the purpose of the tricky code at the end of arch/x86/Kconfig.debug. Without it, the following would be shown: WARNING: unmet direct dependencies detected for FRAME_POINTER because 81d387190039 ("x86/kconfig: Consolidate unwinders into multiple choice selection") removed 'select ARCH_WANT_FRAME_POINTERS'. The correct and more straightforward approach should have been to move it where 'select FRAME_POINTER' is located. Several architectures properly handle the conditional selection of ARCH_WANT_FRAME_POINTERS. For example, 'config UNWINDER_FRAME_POINTER' in arch/arm/Kconfig.debug.
