2018-10-01netlink: add validation function to policyJohannes Berg
Add the ability to have an arbitrary validation function attached to a netlink policy that doesn't already use the validation_data pointer in another way. This can be useful to validate for example the content of a binary attribute, like in nl80211 the "(information) elements", which must be valid streams of "u8 type, u8 length, u8 value[length]".

2018-10-01netlink: add attribute range validation to policyJohannes Berg
Without further bloating the policy structs, we can overload the `validation_data' pointer with a struct of s16 min, max and use those to validate ranges in NLA_{U,S}{8,16,32,64} attributes. It may sound strange to validate NLA_U32 with a s16 max, but in many cases NLA_U32 is used for enums etc. since there's no size benefit in using a smaller attribute width anyway, due to netlink attribute alignment; in cases like that it's still useful, particularly when the attribute really transports an enum value. Doing so lets us remove quite a bit of validation code, if we can be sure that these attributes aren't used by userspace in places where they're ignored today. To achieve all this, split the 'type' field and introduce a new 'validation_type' field which indicates what further validation (beyond the validation prescribed by the type of the attribute) is done. This currently allows for no further validation (the default), as well as min, max and range checks. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

2018-09-28netlink: add nested array policy validationJohannes Berg
Sometimes nested netlink attributes are just used as arrays, with the nla_type() of each not being used; we have this in nl80211 and e.g. NFTA_SET_ELEM_LIST_ELEMENTS. Add the ability to validate this type of message directly in the policy, by adding the type NLA_NESTED_ARRAY which does exactly this: require a first level of nesting but ignore the attribute type, and then inside each require a second level of nested and validate those attributes against a given policy (if present). Note that some nested array types actually require that all of the entries have the same index, this is possible to express in a nested policy already, apart from the validation that only the one allowed type is used.

2018-09-28netlink: allow NLA_NESTED to specify nested policy to validateJohannes Berg
Now that we have a validation_data pointer, and the len field in the policy is unused for NLA_NESTED, we can allow using them both to have nested validation. This can be nice in code, although we still have to use nla_parse_nested() or similar which would also take a policy; however, it also serves as documentation in the policy without requiring a look at the code.

2018-09-28netlink: move extack setting into validate_nla()Johannes Berg
This unifies the code between nla_parse() which sets the bad attribute pointer and an error message, and nla_validate() which only sets the bad attribute pointer. It also cleans up the code for NLA_REJECT and paves the way for nested policy validation, as it will allow us to easily skip setting the "generic" message without any extra args like the **error_msg now, just passing the extack through is now enough. While at it, remove the unnecessary label in nla_parse(). Suggested-by: David Ahern <dsahern@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

2018-09-28netlink: make validation_data constJohannes Berg
The validation data is only used within the policy that should usually already be const, and isn't changed in any code that uses it. Therefore, make the validation_data pointer const. While at it, remove the duplicate variable in the bitfield validation that I'd otherwise have to change to const.

2018-09-18netlink: add ethernet address policy typesJohannes Berg
Commonly, ethernet addresses are just using a policy of { .len = ETH_ALEN } which leaves userspace free to send more data than it should, which may hide bugs. Introduce NLA_EXACT_LEN which checks for exact size, rejecting the attribute if it's not exactly that length. Also add NLA_EXACT_LEN_WARN which requires the minimum length and will warn on longer attributes, for backward compatibility. Use these to define NLA_POLICY_ETH_ADDR (new strict policy) and NLA_POLICY_ETH_ADDR_COMPAT (compatible policy with warning); these are used like this: static const struct nla_policy <name>[...] = { [NL_ATTR_NAME] = NLA_POLICY_ETH_ADDR, ... }; Signed-off-by: Johannes Berg <johannes.berg@intel.com> Reviewed-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.

2018-09-18netlink: add NLA_REJECT policy typeJohannes Berg
In some situations some netlink attributes may be used for output only (kernel->userspace) or may be reserved for future use. It's then helpful to be able to prevent userspace from using them in messages sent to the kernel, since they'd otherwise be ignored and any future will become impossible if this happens. Add NLA_REJECT to the policy which does nothing but reject (with EINVAL) validation of any messages containing this attribute. Allow for returning a specific extended ACK error message in the validation_data pointer. While at it clear up the documentation a bit - the NLA_BITFIELD32 documentation was added to the list of len field descriptions. Also, use NL_SET_BAD_ATTR() in one place where it's open-coded. The specific case I have in mind now is a shared nested attribute containing request/response data, and it would be pointless and potentially confusing to have userspace include response data in the messages that actually contain a request.

2018-08-22lib/rhashtable: guarantee initial hashtable allocationDavidlohr Bueso
rhashtable_init() may fail due to -ENOMEM, thus making the entire api unusable. This patch removes this scenario, however unlikely. In order to guarantee memory allocation, this patch always ends up doing GFP_KERNEL|__GFP_NOFAIL for both the tbl as well as alloc_bucket_spinlocks(). Upon the first table allocation failure, we shrink the size to the smallest value that makes sense and retry with __GFP_NOFAIL semantics. With the defaults, this means that from 64 buckets, we retry with only 4. Any later issues regarding performance due to collisions or larger table resizing (when more memory becomes available) is the least of our problems.

2018-08-22lib/rhashtable: simplify bucket_table_alloc()Davidlohr Bueso
As of ce91f6ee5b3b ("mm: kvmalloc does not fallback to vmalloc for incompatible gfp flags") we can simplify the caller and trust kvzalloc() to just do the right thing. For the case of the GFP_ATOMIC context, we can drop the __GFP_NORETRY flag for obvious reasons, and for the __GFP_NOWARN case, however, it is changed such that the caller passes the flag instead of making bucket_table_alloc() handle it. This slightly changes the gfp flags passed on to nested_table_alloc() as it will now also use GFP_ATOMIC | __GFP_NOWARN. However, I consider this a positive consequence as for the same reasons we want nowarn semantics in bucket_table_alloc().

2018-08-22lib: add crc64 calculation routinesColy Li
Patch series "add crc64 calculation as kernel library", v5. This patchset adds basic implementation of crc64 calculation as a Linux kernel library. Since bcache already does crc64 by itself, this patchset also modifies bcache code to use the new crc64 library routine. Currently bcache is the only user of crc64 calculation, another potential user is bcachefs which is on the way to be in mainline kernel. Therefore it makes sense to make crc64 calculation to be a public library. bcache uses crc64 as storage checksum, if a change of crc lib routines results an inconsistent result, the unmatched checksum may make bcache 'think' the on-disk is corrupted, such a change should be avoided or detected as early as possible. Therefore a patch is being prepared which adds a crc test framework, to check consistency of different calculations. This patch (of 2): Add the re-write crc64 calculation routines for Linux kernel. The CRC64 polynomical arithmetic follows ECMA-182 specification, inspired by CRC paper of Dr. Ross N. Williams (see http://www.ross.net/crc/download/crc_v3.txt) and other public domain implementations. All the changes work in this way, - When Linux kernel is built, host program lib/gen_crc64table.c will be compiled to lib/gen_crc64table and executed. - The output of gen_crc64table execution is an array called as lookup table (a.k.a POLY 0x42f0e1eba9ea369) which contain 256 64-bit long numbers, this table is dumped into header file lib/crc64table.h. - Then the header file is included by lib/crc64.c for normal 64bit crc calculation. - Function declaration of the crc64 calculation routines is placed in include/linux/crc64.h Currently bcache is the only user of crc64_be(), another potential user is bcachefs which is on the way to be in mainline kernel. Therefore it makes sense to move crc64 calculation into lib/crc64.c as public code.

2018-08-18deprecate the '__deprecated' attribute warnings entirely and for goodLinus Torvalds
We haven't had lots of deprecation warnings lately, but the rdma use of it made them flare up again. They are not useful. They annoy everybody, and nobody ever does anything about them, because it's always "somebody elses problem". And when people start thinking that warnings are normal, they stop looking at them, and the real warnings that mean something go unnoticed. If you want to get rid of a function, just get rid of it. Convert every user to the new world order. And if you can't do that, then don't annoy everybody else with your marking that says "I couldn't be bothered to fix this, so I'll just spam everybody elses build logs with warnings about my laziness". Make a kernelnewbies wiki page about things that could be cleaned up, write a blog post about it, or talk to people on the mailing lists. But don't add warnings to the kernel build about cleanup that you think should happen but you aren't doing yourself. Don't. Just don't. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2018-08-16ila: make lockdep happy againCong Wang
Previously, alloc_ila_locks() and bucket_table_alloc() call spin_lock_init() separately, therefore they have two different lock names and lock class keys. However, after commit b893281715ab ("ila: Call library function alloc_bucket_locks") they both call helper alloc_bucket_spinlocks() which now only has one lock name and lock class key. This causes a few bogus lockdep warnings as reported by syzbot. Fix this by making alloc_bucket_locks() a macro and pass declaration name as lock name and a static lock class key inside the macro. Fixes: b893281715ab ("ila: Call library function alloc_bucket_locks") Reported-by: <syzbot+b66a5a554991a8ed027c@syzkaller.appspotmail.com> Cc: Tom Herbert <tom@quantonium.net> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
