Since in theory a server could respond with compressed read responses even if not requested on read request (assuming that a compression negcontext is sent in negotiate protocol) - do not send compression information during negotiate protocol unless the user asks for compression explicitly (compression is experimental), and add a mount warning that compression is experimental.

There is a special ACE used by some servers to allow the mode bits to be stored. This can be especially helpful in scenarios in which the client is trusted, and access checking on the client vs the POSIX mode bits is sufficient. Add mount option to allow enabling this behavior. Follow on patch will add support for chmod and queryinfo (stat) by retrieving the POSIX mode bits from the special ACE, SID: S-1-5-88-3 See e.g. https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/hh509017(v=ws.10)Signed-off-by: NSteve French <stfrench@microsoft.com> Reviewed-by: NRonnie Sahlberg <lsahlber@redhat.com>

There is a race condition with how we send (or supress and don't send) smb echos that will cause the client to incorrectly think the server is unresponsive and thus needs to be reconnected. Summary of the race condition: 1) Daisy chaining scheduling creates a gap. 2) If traffic comes unfortunate shortly after the last echo, the planned echo is suppressed. 3) Due to the gap, the next echo transmission is delayed until after the timeout, which is set hard to twice the echo interval. This is fixed by changing the timeouts from 2 to three times the echo interval.

When using multidialect negotiate (default or specifying vers=3.0 which allows any smb3 dialect), fix how we check for an existing server session. Before this fix if you mounted a second time to the same server (e.g. a different share on the same server) we would only reuse the existing smb session if a single dialect were requested (e.g. specifying vers=2.1 or vers=3.0 or vers=3.1.1 on the mount command). If a default mount (e.g. not specifying vers=) is done then would always create a new socket connection and SMB3 (or SMB3.1.1) session each time we connect to a different share on the same server rather than reusing the existing one.

When the blk-mq debugfs file creation logic was "cleaned up" it was cleaned up too much, causing the queue file to not be created in the correct location.

由 Zhang Lei 提交于
The original implementation of vq_present() relied on aggressive inlining in order for the compiler to know that the code is correct, due to some const-casting issues. This was causing sparse and clang to complain, while GCC compiled cleanly. Commit 0c529ff7 addressed this problem, but since vq_present() is no longer a function, there is now no implicit casting of the returned value to the return type (bool). In set_sve_vls(), this uncast bit value is compared against a bool, and so may spuriously compare as unequal when both are nonzero. As a result, KVM may reject valid SVE vector length configurations as invalid, and vice versa. Fix it by forcing the returned value to a bool.

It is possible for an irq triggered by channel0 to be received later after clks are disabled once firmware loaded during sdma probe. If that happens then clearing them by writing to SDMA_H_INTR won't work and the kernel will hang processing infinite interrupts. Actually, don't need interrupt triggered on channel0 since it's pollling SDMA_H_STATSTOP to know channel0 done rather than interrupt in current code, just clear BD_INTR to disable channel0 interrupt to avoid the above case. This issue was brought by commit 1d069bfa ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") which didn't take care the above case.
