+Subject: [PATCH 01/27] MPILIB: Provide count_leading/trailing_zeros() based
+ on arch functions
-Export some more symbols for use by the DSA key subtype.
+Provide count_leading/trailing_zeros() macros based on extant arch bit scanning
+functions rather than reimplementing from scratch in MPILIB.
+
+Whilst we're at it, turn count_foo_zeros(n, x) into n = count_foo_zeros(x).
+
+Also move the definition to asm-generic as other people may be interested in
+using it.

+ (*) MODULES_USE_ELF_REL
+
+ Arches define this if their modules can contain REL records. This causes
+ the Elf_Rel mapping to be emitted and allows apply_relocate() to be
+ defined by the arch rather than have the core emit an error message.
+Note that it is possible to allow both REL and RELA records: m68k and mips are
+two arches that do this.
+
+With this, some arch asm/module.h files can be deleted entirely and replaced
+with a generic-y marker in the arch Kbuild file.
+
+Additionally, I have removed the bits from m32r and score that handle the
+unsupported type of relocation record as that's now handled centrally.

+Subject: [PATCH 21/27] MODSIGN: Automatically generate module signing keys if
+ missing
+
+Automatically generate keys for module signing if they're absent so that
+allyesconfig doesn't break. The builder should consider generating their own
+keyrings, however, so that the keys are appropriately named and any extra keys
+required get imported.
+
+Also change the names of the keyring files to modsign.pub and modsign.sec so
+that they are then a more obvious what they're about and add a dependency for
+the signing rules on the keyring files so that the signatures get regenerated
+if the keyrings change.

- missing
-
-Automatically generate keys for module signing if they're absent so that
-allyesconfig doesn't break. The builder should consider generating their own
-keyrings, however, so that the keys are appropriately named and any extra keys
-required get imported.
-
-Also change the names of the keyring files to modsign.pub and modsign.sec so
-that they are then a more obvious what they're about and add a dependency for
-the signing rules on the keyring files so that the signatures get regenerated
-if the keyrings change.

-Subject: [PATCH 32/36] PGPLIB: Check the length in a packet or subpacket
-
-Check the length in a packet or subpacket to make sure there isn't an overflow
-should the length not fit into the lower 31 bits of an integer.
-
-It is possible that both pgp_parse_packet_header() and
-pgp_parse_sig_subpkt_header() could see packets that purport to be >2G in size.
-Normally this will not be a problem because EBADMSG is indicated if the size
-indicated is greater than the remnant size of the data - but just in case we do
-end up parsing a >2G blob, a couple of simple checks can prevent an overflow
-from occurring.

-Subject: [PATCH 36/36] PGPLIB: Adjust error handling
-
-Adjust the error handling in the following ways:
-
- (1) When parsing signature subpacket header, do the size checks before
- accessing the subpacket type (which is in the subpacket payload governed
- by the size).
-
- (2) Indicate ENOPKG when we are asked to use a public key algorithm we don't
- support rather than returning ENOKEY.
-
- (3) Indicate EKEYREJECTED if the key that matches the signature demands a
- different key algorithm to the signature.
-
- (4) Indicate ENOMSG if the signature blob does not contain a signature
- packet. Possibly this should be EBADMSG - though that causes the next
- packet parser to be tried if available.
-
- (5) Give a better debug message in the case of an unsupported hash.
-
- (6) Don't return keyring-related errors when searching for a key containing
- the public key (EACCES, ENOTDIR, EAGAIN), but rather map them to ENOKEY.
- Possibly EACCES should be passed through as you also get that if there
- *is* a matching key, but it cannot be accessed.
