19 months agommc: atmel-mci: fix race between stop command and start of next command
Tobias Schramm [Fri, 30 Dec 2022 19:43:15 +0000 (20:43 +0100)]
mmc: atmel-mci: fix race between stop command and start of next command

This commit fixes a race between completion of stop command and start of a
new command.
Previously the command ready interrupt was enabled before stop command
was written to the command register. This caused the command ready
interrupt to fire immediately since the CMDRDY flag is asserted constantly
while there is no command in progress.
Consequently the command state machine will immediately advance to the
next state when the tasklet function is executed again, no matter
actual completion state of the stop command.
Thus a new command can then be dispatched immediately, interrupting and
corrupting the stop command on the CMD line.
Fix that by dropping the command ready interrupt enable before calling
atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the
command ready interrupt, no further writes to ATMCI_IER are necessary.

mmc: sdhci-pci: Replace SDHCI_QUIRK_MISSING_CAPS for Ricoh controller

SDHCI_QUIRK_MISSING_CAPS is not needed because __sdhci_read_caps() can be
called instead.

In preparation to get rid of SDHCI_QUIRK_MISSING_CAPS, replace
SDHCI_QUIRK_MISSING_CAPS with __sdhci_read_caps() for Ricoh SDHCI
controller.

__sdhci_read_caps() is also called from sdhci_setup_host() via
sdhci_read_caps(), however only the first call to __sdhci_read_caps() does
anything because after that host->read_caps has been set to true.

Note, __sdhci_read_caps() does more than just set host->caps, such as do a
reset, so calling __sdhci_read_caps() earlier could have unforeseen
side-effects. However the code flow has been reviewed with that in mind.

ext4: deal with legacy signed xattr name hash values

We potentially have old hashes of the xattr names generated on systems
with signed 'char' types.  Now that everybody uses '-funsigned-char',
those hashes will no longer match.

This only happens if you use xattrs names that have the high bit set,
which probably doesn't happen in practice, but the xfstest generic/454
shows it.

Instead of adding a new "signed xattr hash filesystem" bit and having to
deal with all the possible combinations, just calculate the hash both
ways if the first one fails, and always generate new hashes with the
proper unsigned char version.

io_uring/poll: don't reissue in case of poll race on multishot request

A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.

A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests.

19 months agomisc: fastrpc: Pass bitfield into qcom_scm_assign_mem
Elliot Berman [Thu, 12 Jan 2023 18:23:12 +0000 (10:23 -0800)]
misc: fastrpc: Pass bitfield into qcom_scm_assign_mem

The srcvm parameter of qcom_scm_assign_mem is a pointer to a bitfield of
VMIDs. The  bitfield is updated with which VMIDs have permissions
after the qcom_scm_assign_mem call. This makes it simpler for clients to
make qcom_scm_assign_mem calls later, they always pass in same srcvm
bitfield and do not need to closely track whether memory was originally
shared.

When restoring permissions to HLOS, fastrpc is incorrectly using the
first VMID directly -- neither the BIT nor the other possible VMIDs the
memory was already assigned to.  We already have a field intended for
this purpose: "perms" in the struct fastrpc_channel_ctx, but it was
never used. Start using the perms field.

all safety features were enabled by default.

support. If the automotive safety package bit is set in the hardware
features register the safety feature callback is called for the platform,
