2020-10-07SUNRPC: Implement a xdr_page_pos() functionAnna Schumaker2-0/+14
I'll need this for READ_PLUS to help figure out the offset where page data is stored at, but it might also be useful for other things. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

I'm going to need this bit of code in a few places for READ_PLUS decoding, so let's make it a helper function. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

We are generating incorrect path in case of rename retry because we are restarting from wrong dentry. We should restart from the dentry which was received in the call to nfs_path.

2020-10-02fs: nfs: return per memcg count for xattr shrinkersYang Shi1-2/+2
The list_lru_count() returns the pre node count, but the new xattr shrinkers are memcg aware, so the shrinkers should return per memcg count by calling list_lru_shrink_count() instead. Otherwise over-shrink might be experienced. The problem was spotted by visual code inspection.

2020-10-02NFSv4: Wait for stateid updates after CLOSE/OPEN_DOWNGRADEBenjamin Coddington3-34/+56
Since commit 0e0cb35b417f ("NFSv4: Handle NFS4ERR_OLD_STATEID in CLOSE/OPEN_DOWNGRADE") the following livelock may occur if a CLOSE races with the update of the nfs_state: Process 1 Process 2 Server ========= ========= ======== OPEN file OPEN file Reply OPEN (1) Reply OPEN (2) Update state (1) CLOSE file (1) Reply OLD_STATEID (1) CLOSE file (2) Reply CLOSE (-1) Update state (2) wait for state change OPEN file wake CLOSE file OPEN file wake CLOSE file ... ... We can avoid this situation by not issuing an immediate retry with a bumped seqid when CLOSE/OPEN_DOWNGRADE receives NFS4ERR_OLD_STATEID. Instead, take the same approach used by OPEN and wait at least 5 seconds for outstanding stateid updates to complete if we can detect that we're out of sequence. Note that after this change it is still possible (though unlikely) that CLOSE waits a full 5 seconds, bumps the seqid, and retries -- and that attempt races with another OPEN at the same time. In order to avoid this race (which would result in the livelock), update nfs_need_update_open_stateid() to handle the case where: - the state is NFS_OPEN_STATE, and - the stateid doesn't match the current open stateid Finally, nfs_need_update_open_stateid() is modified to be idempotent and renamed to better suit the purpose of signaling that the stateid passed is the next stateid in sequence.

2020-10-02nfs: remove incorrect fallthrough labelNick Desaulniers1-1/+1
There is no case after the default from which to fallthrough to. Clang will error in this case (unhelpfully without context, see link below) and GCC will with -Wswitch-unreachable. The previous commit should have just replaced the comment with a break statement. If we consider implicit fallthrough to be a design mistake of C, then all case statements should be terminated with one of the following statements: * break * continue * return * fallthrough * goto * (call of function with __attribute__(__noreturn__)) Fixes: 2a1390c95a69 ("nfs: Convert to use the preferred fallthrough macro") Link: https://bugs.llvm.org/show_bug.cgi?id=47539 Acked-by: Gustavo A.

2020-09-24NFSv4: make cache consistency bitmask dynamicOlga Kornievskaia2-6/+45
Client uses static bitmask for GETATTR on CLOSE/WRITE/DELEGRETURN and ignores the fact that it might have some attributes marked invalid in its cache. Compared to v3 where all attributes are retrieved in postop attributes, v4's cache is frequently out of sync and leads to standalone GETATTRs being sent to the server. Instead, in addition to the minimum cache consistency attributes also check cache_validity and adjust the GETATTR request accordingly.

2020-09-21SUNRPC dont update timeout value on connection resetOlga Kornievskaia1-1/+2
Current behaviour: every time a v3 operation is re-sent to the server we update (double) the timeout. There is no distinction between whether or not the previous timer had expired before the re-sent happened. Here's the scenario: 1. Client sends a v3 operation 2. Server RST-s the connection (prior to the timeout) (eg., connection is immediately reset) 3. Client re-sends a v3 operation but the timeout is now 120sec. As a result, an application sees 2mins pause before a retry in case server again does not reply. Where as if a connection reset didn't change the timeout value, the client would have re-tried (the 3rd time) after 60secs.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "A handful of fixes to address a string of mistakes in the mechanism for device-mapper to determine if its component devices are dax capable. - Fix an original bug in device-mapper table reference counting when interrogating dax capability in the component device. This bug was hidden by the following bug. - Fix device-mapper to use the proper helper (dax_supported() instead of the leaf helper generic_fsdax_supported()) to determine dax operation of a stacked block device configuration. The original implementation is only valid for one level of dax-capable block device stacking. This bug was discovered while fixing the below regression. - Fix an infinite recursion regression introduced by broken attempts to quiet the generic_fsdax_supported() path and make it bail out before logging "dax capability not found" errors" * tag 'libnvdimm-fixes-5.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: dax: Fix stack overflow when mounting fsdax pmem device dm: Call proper helper to determine dax support dm/dax: Fix table reference counts

git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fixes from Palmer Dabbelt: - A fix for a lockdep issue to avoid an asserting triggering during early boot. There shouldn't be any incorrect behavior as the system isn't concurrent at the time. - The addition of a missing fence when installing early fixmap mappings. - A corretion to the K210 device tree's interrupt map. - A fix for M-mode timer handling on the K210. * tag 'riscv-for-linus-5.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: RISC-V: Resurrect the MMIO timer implementation for M-mode systems riscv: Fix Kendryte K210 device tree riscv: Add sfence.vma after early page table changes RISC-V: Take text_mutex in ftrace_init_nop()
