[PATCH BlueZ v2 0/5] shared: Use util_iov helpers in gatt-db, hog, asha and micp

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This continues the conversion of the GATT code in src/shared to the
util_iov_pull_* and util_iov_push_* helpers, so that the bounds check is
part of the access, now for gatt-db and the HoG, ASHA and MICP profiles.

The conversions are meant to be behavior preserving and are covered by
the existing unit tests (test-gatt, test-hog, test-micp). The existing
code already checked the lengths in the HoG and ASHA readers, so no new
tests were added for them.

The one bug found is in micp: a Mute State notification with no value
made micp_mute_state_notify read a byte past the value. It is fixed, but
there is no test for it since the scripted test-micp client flow does
not deliver a notification to that handler, so it could not be
reproduced.

bap, rap and the remaining profiles will follow in separate series.

v2:
 - gatt-db: don't update the database hash from incomplete input when
   allocating a hash entry fails, keep the current hash and retry the
   update later (review feedback on v1).

Luiz Augusto von Dentz (5):
  shared/gatt-db: Use util_iov helpers to build and parse values
  shared/hog: Use util_iov helpers to parse characteristic values
  shared/asha: Use util_iov helpers to parse characteristic values
  shared/micp: Fix reading Mute State from an empty notification
  shared/micp: Use util_iov_pull_mem instead of a local helper

[PATCH BlueZ v2 1/5] shared/gatt-db: Use util_iov helpers to build and parse values

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Build the hash input, characteristic, include and service declarations
with util_iov_push_*, and parse declaration values in the
gatt_db_attribute_get_*_data functions with util_iov_pull_* so they are
checked against the stored value length.

The hash input allocation is now also checked. If it fails the hash is
not updated from the incomplete input and the update is retried later.

[PATCH BlueZ v2 2/5] shared/hog: Use util_iov helpers to parse characteristic values

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Parse Report Reference, External Report Reference, HID Information, SCI
Mode, SCI Information and Protocol Mode values with util_iov_pull_*
instead of indexing the value, so every field is checked against the
length of the value that was read.

[PATCH BlueZ v2 4/5] shared/micp: Fix reading Mute State from an empty notification

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

micp_mute_state_notify copied one byte from the notification value
without checking its length, so a notification with no value made it
read past the value.

Pull the byte from the value instead and ignore the notification if it
is missing.

Fixes: 5c788b73 ("src/shared/micp.c: To implement MICP profile MICS service")

[PATCH BlueZ v2 5/5] shared/micp: Use util_iov_pull_mem instead of a local helper

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Drop the local iov_pull_mem, which duplicates util_iov_pull_mem.
