* Support hardware rate limiting (pacing) with TLS offload.John Baldwin2020-10-292-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add a new send tag type for a send tag that supports both rate limiting (packet pacing) and TLS offload (mostly similar to D22669 but adds a separate structure when allocating the new tag type). - When allocating a send tag for TLS offload, check to see if the connection already has a pacing rate. If so, allocate a tag that supports both rate limiting and TLS offload rather than a plain TLS offload tag. - When setting an initial rate on an existing ifnet KTLS connection, set the rate in the TCP control block inp and then reset the TLS send tag (via ktls_output_eagain) to reallocate a TLS + ratelimit send tag. This allocates the TLS send tag asynchronously from a task queue, so the TLS rate limit tag alloc is always sleepable. - When modifying a rate on a connection using KTLS, look for a TLS send tag. If the send tag is only a plain TLS send tag, assume we failed to allocate a TLS ratelimit tag (either during the TCP_TXTLS_ENABLE socket option, or during the send tag reset triggered by ktls_output_eagain) and ignore the new rate. If the send tag is a ratelimit TLS send tag, change the rate on the TLS tag and leave the inp tag alone. - Lock the inp lock when setting sb_tls_info for a socket send buffer so that the routines in tcp_ratelimit can safely dereference the pointer without needing to grab the socket buffer lock. - Add an IFCAP_TXTLS_RTLMT capability flag and associated administrative controls in ifconfig(8). TLS rate limit tags are only allocated if this capability is enabled. Note that TLS offload (whether unlimited or rate limited) always requires IFCAP_TXTLS[46].

* Replace literal uses of /usr/local in C sources with _PATH_LOCALBASEStefan Eßer2020-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Literal references to /usr/local exist in a large number of files in the FreeBSD base system. Many are in contributed software, in configuration files, or in the documentation, but 19 uses have been identified in C source files or headers outside the contrib and sys/contrib directories. This commit makes it possible to set _PATH_LOCALBASE in paths.h to use a different prefix for locally installed software. In order to avoid changes to openssh source files, LOCALBASE is passed to the build via Makefiles under src/secure. While _PATH_LOCALBASE could have been used here, there is precedent in the construction of the path used to a xauth program which depends on the LOCALBASE value passed on the compiler command line to select a non-default directory. This could be changed in a later commit to make the openssh build consistently use _PATH_LOCALBASE. It is considered out-of-scope for this commit.

* Various new check-hash checks have been added to the UFS filesystemKirk McKusick2020-10-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | over various major releases. Superblock check hashes were added for the 12 release and cylinder-group and inode check hashes will appear in the 13 release. When a disk with a UFS filesystem is writably mounted, the kernel clears the feature flags for anything that it does not support. For example, if a UFS disk from a 12-stable kernel is mounted on an 11-stable system, the 11-stable kernel will clear the flag in the filesystem superblock that indicates that superblock check-hashs are being maintained. Thus if the disk is later moved back to a 12-stable system, the 12-stable system will know to ignore its incorrect check-hash. If the only filesystem modification done on the earlier kernel is to run a utility such as growfs(8) that modifies the superblock but neither updates the check-hash nor clears the feature flag indicating that it does not support the check-hash, the disk will fail to mount if it is moved back to its original newer kernel. This patch moves the code that clears the filesystem feature flags from the mount code (ffs_mountfs()) to the code that reads the superblock (ffs_sbget()). As ffs_sbget() is used by the kernel mount code and is imported into libufs(3), all the filesystem utilities will now also clear these flags when they make modifications to the filesystem. As suggested by John Baldwin, fsck_ffs(8) has been changed to accept and repair bad superblock check-hashes rather than refusing to run. This change allows fsck to recover filesystems that have been impacted by utilities older than those created after this change and is a sensible thing to do in any event.

Even with the latest optimizations to atf-sh this test still takes a few seconds to startup in QEMU. Re-writing it in C reduces the runtime for a single test from about 2-3 seconds to less than .5 seconds. Since there are ~80 tests, this adds up to about 3-4 minutes. This may not seem like a big speedup, but before the recent optimizations to avoid atf_get_srcdir, each test took almost 100 seconds on QEMU RISC-V instead of 3. This also significantly reduces the time it takes to list the available test cases, which speeds up running the tests via kyua: ``` root@qemu-riscv64-alex:~ # /usr/bin/time kyua test -k /usr/tests/sbin/pfctl/Kyuafile pfctl_test_old ... 158/158 passed (0 failed) 332.08 real 42.58 user 286.17 sys root@qemu-riscv64-alex:~ # /usr/bin/time kyua test -k /usr/tests/sbin/pfctl/Kyuafile pfctl_test 158/158 passed (0 failed) 24.96 real 9.75 user 14.26 sys root@qemu-riscv64-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test pf1001 pfctl_test: WARNING: Running test cases outside of kyua(1) is unsupported pfctl_test: WARNING: No isolation nor timeout control is being applied; you may get unexpected failures; see atf-test-case(4) Running pfctl -o none -nvf /usr/tests/sbin/pfctl/./files/pf1001.in --- binat on em0 inet6 from fc00::/64 to any -> fc00:0:0:1::/64 binat on em0 inet6 from any to fc00:0:0:1::/64 -> fc00::/64 --- passed 0.17 real 0.06 user 0.08 sys root@qemu-riscv64-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test_old pf1001 pfctl_test_old: WARNING: Running test cases outside of kyua(1) is unsupported pfctl_test_old: WARNING: No isolation nor timeout control is being applied; you may get unexpected failures; see atf-test-case(4) Id Refs Name 141 1 pf Executing command [ pfctl -o none -nvf - ] passed 1.73 real 0.25 user 1.41 sys root@qemu-riscv64-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test_old -l > /dev/null 24.36 real 2.26 user 21.86 sys root@qemu-riscv64-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test -l > /dev/null 0.04 real 0.02 user 0.01 sys ``` The speedups are even more noticeable on CHERI-RISC-V (since QEMU runs slower when emulating CHERI instructions): ``` root@qemu-cheri-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test_new -l > /dev/null 0.51 real 0.49 user 0.00 sys root@qemu-cheri-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test -l > /dev/null 34.20 real 32.69 user 0.16 sys root@qemu-cheri-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test pf1001 pfctl_test: WARNING: Running test cases outside of kyua(1) is unsupported pfctl_test: WARNING: No isolation nor timeout control is being applied; you may get unexpected failures; see atf-test-case(4) Id Refs Name 147 1 pf Executing command [ pfctl -o none -nvf - ] passed 5.74 real 5.41 user 0.03 sys root@qemu-cheri-alex:/usr/tests/sbin/pfctl # /usr/bin/time ./pfctl_test_new pf1001 pfctl_test_new: WARNING: Running test cases outside of kyua(1) is unsupported pfctl_test_new: WARNING: No isolation nor timeout control is being applied; you may get unexpected failures; see atf-test-case(4) Running pfctl -o none -nvf /usr/tests/sbin/pfctl/./files/pf1001.in --- binat on em0 inet6 from fc00::/64 to any -> fc00:0:0:1::/64 binat on em0 inet6 from any to fc00:0:0:1::/64 -> fc00::/64 --- passed 0.68 real 0.66 user 0.00 sys root@qemu-cheri-alex:/usr/tests/sbin/pfctl # ``` Reviewed By: kp Differential Revision: https://reviews.freebsd.org/D26779 Notes: svn path=/head/; revision=366708

* Enable iterating all sysctls, even ones with CTLFLAG_SKIPRyan Moeller2020-10-051-14/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Add an "nextnoskip" sysctl that allows for listing of sysctls intended to be normally skipped for cost reasons. This makes it so the names/descriptions of those sysctls can be discovered with sysctl -aN/sysctl -ad/sysctl -at. It also makes it so children are visited when a node flagged with CTLFLAG_SKIP is explicitly requested. The intended use case is to mark the root "kstat" node with CTLFLAG_SKIP so that the extensive and expensive stats are skipped by default but may still be easily obtained without having to know them all (which may not even be possible) and request each one-by-one.

* devfs.rules: unhide pf in vnet jailsKristof Provost2020-10-051-0/+4
| | | | | | | | | | | | | /dev/pf is usable in vnet jails, so don't hide the node there. We shouldn't expose /dev/pf in regular jails, as that gives them control over the host (or parent vnet jail) firewall.
