* qed: Prevent over-usage of vlan credits by PFYuval Mintz2016-07-30
| | | | | | | | | | | | | | | | Each PF/VF has a limited number of vlan filters for configuration purposes; This information is passed to qede and is used to prevent over-usage - once a vlan is to be configured and no filter credit is available, the driver would switch into working in vlan-promisc mode. Problem is the credit pool is shared by both PFs and VFs, and currently PFs aren't deducting the filters that are reserved for their VFs from their quota, which may lead to some vlan filters failing unknowingly due to lack of credit.

* qed: Correct min bandwidth for 100gYuval Mintz2016-07-30
| | | | | | | | | | Driver uses reverse logic when checking if minimum bandwidth configuration applied, causing it to configure the guarantee only on the first hw-function.

* qed: Don't over-do producer cleanup for RxYuval Mintz2016-07-30
| | | | | | | | | | Before requesting the firmware to start Rx queues, driver goes and sets the queue producer in the device to 0. But while the producer is 32-bit, the driver currently clears 64 bits, effectively zeroing an additional CID's producer as well.

* qed: Fix removal of spoof checking for VFsYuval Mintz2016-07-30
| | | | | | | | | | | | Driver has reverse logic for checking the result of the spoof-checking configuration. As a result, it would log that the configuration failed [even though it succeeded], and will no longer do anything when requested to remove the configuration, as it's accounting of the feature will be incorrect.

* qede: Don't try removing unconfigured vlansYuval Mintz2016-07-30
| | | | | | | | | | | | | | | | | | | | As part of ndo_vlan_rx_kill_vid() implementation, qede is requesting firmware to remove the vlan filter. This currently happens even if the vlan wasn't previously added [In case device ran out of vlan credits]. For PFs this doesn't cause any issues as the firmware would simply ignore the removal request. But for VFs their parent PF is holding an accounting of the configured vlans, and such a request would cause the PF to fail the VF's removal request. Simply fix this for both PFs & VFs and don't remove filters that were not previously added.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull audit updates from Paul Moore: "Six audit patches for 4.8. There are a couple of style and minor whitespace tweaks for the logs, as well as a minor fixup to catch errors on user filter rules, however the major improvements are a fix to the s390 syscall argument masking code (reviewed by the nice s390 folks), some consolidation around the exclude filtering (less code, always a win), and a double-fetch fix for recording the execve arguments" * 'stable-4.8' of git://git.infradead.org/users/pcmoore/audit: audit: fix a double fetch in audit_log_single_execve_arg() audit: fix whitespace in CWD record audit: add fields to exclude filter by reusing user filter s390: ensure that syscall arguments are properly masked on s390 audit: fix some horrible switch statement style crimes audit: fixup: log on errors from filter user rules
| * audit: fix a double fetch in audit_log_single_execve_arg()Paul Moore2016-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a double fetch problem in audit_log_single_execve_arg() where we first check the execve(2) argumnets for any "bad" characters which would require hex encoding and then re-fetch the arguments for logging in the audit record[1]. Of course this leaves a window of opportunity for an unsavory application to munge with the data. This patch reworks things by only fetching the argument data once[2] into a buffer where it is scanned and logged into the audit records(s). In addition to fixing the double fetch, this patch improves on the original code in a few other ways: better handling of large arguments which require encoding, stricter record length checking, and some performance improvements (completely unverified, but we got rid of some strlen() calls, that's got to be a good thing). As part of the development of this patch, I've also created a basic regression test for the audit-testsuite, the test can be tracked on GitHub at the following link: * https://github.com/linux-audit/audit-testsuite/issues/25 [1] If you pay careful attention, there is actually a triple fetch problem due to a strnlen_user() call at the top of the function. [2] This is a tiny white lie, we do make a call to strnlen_user() prior to fetching the argument data. I don't like it, but due to the way the audit record is structured we really have no choice unless we copy the entire argument at once (which would require a rather wasteful allocation). The good news is that with this patch the kernel no longer relies on this strnlen_user() value for anything beyond recording it in the log, we also update it with a trustworthy value whenever possible.

In the process several small drivers bugs relating to error handling this flow are fixed. For now the flag TPM_OPS_AUTO_STARTUP is optional to allow a staged driver roll out, but ultimately all drivers should use this flow and the flag removed. Some drivers still do not implement the startup sequence at all and will need to be tested with it enabled.

| * | apparmor: fix replacement bug that adds new child to old parentJohn Johansen2016-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When set atomic replacement is used and the parent is updated before the child, and the child did not exist in the old parent so there is no direct replacement then the new child is incorrectly added to the old parent. This results in the new parent not having the child(ren) that it should and the old parent when being destroyed asserting the following error.

| | * | modsign: Make sign-file determine the format of the X.509 certDavid Howells2016-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sign-file determine the format of the X.509 certificate by reading the first two bytes and seeing if the first byte is 0x30 and the second 0x81-0x84. If this is the case, assume it's DER encoded, otherwise assume it to be PEM encoded. Without this, it gets awkward to deal with the error messages from d2i_X509_bio() when we want to call BIO_reset() and then PEM_read_bio() in case the certificate was PEM encoded rather than X.509 encoded.
