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.

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.

21 months agomisc: fastrpc: Fix use-after-free and race in fastrpc_map_find

misc: fastrpc: Fix use-after-free and race in fastrpc_map_find

Currently, there is a race window between the point when the mutex is
unlocked in fastrpc_map_lookup and the reference count increasing
(fastrpc_map_get) in fastrpc_map_find, which can also lead to
use-after-free.

So lets merge fastrpc_map_find into fastrpc_map_lookup which allows us
to both protect the maps list by also taking the &fl->lock spinlock and
the reference count, since the spinlock will be released only after.
Add take_ref argument to make this suitable for all callers.

Fixes: 8f6c1d8c4f0c ("misc: fastrpc: Add fdlist implementation")
