tweewide: Fix most Shebang lines

2021-05-22T08:59:50+00:00

commit c25ce589dca10d64dde139ae093abc258a32869c upstream. Change every shebang which does not need an argument to use /usr/bin/env. This is needed as not every distro has everything under /usr/bin, sometimes not even bash. Signed-off-by: Finn Behrens Signed-off-by: Masahiro Yamada Signed-off-by: Greg Kroah-Hartman

tc-testing: fix build of eBPF programs

2019-11-24T07:20:29+00:00

[ Upstream commit cf5eafbfa586d030f9321cee516b91d089e38280 ] rely on uAPI headers in the current kernel tree, rather than requiring the correct version installed on the test system. While at it, group all sections in a single binary and test the 'section' parameter. Reported-by: Lucas Bates Signed-off-by: Davide Caratti Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

net/sched: act_sample: fix divide by zero in the traffic path

2019-04-17T06:38:41+00:00

[ Upstream commit fae2708174ae95d98d19f194e03d6e8f688ae195 ] the control path of 'sample' action does not validate the value of 'rate' provided by the user, but then it uses it as divisor in the traffic path. Validate it in tcf_sample_init(), and return -EINVAL with a proper extack message in case that value is zero, to fix a splat with the script below: # tc f a dev test0 egress matchall action sample rate 0 group 1 index 2 # tc -s a s action sample total acts 1 action order 0: sample rate 1/0 group 1 pipe index 2 ref 1 bind 1 installed 19 sec used 19 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 # ping 192.0.2.1 -I test0 -c1 -q divide error: 0000 [#1] SMP PTI CPU: 1 PID: 6192 Comm: ping Not tainted 5.1.0-rc2.diag2+ #591 Hardware name: Red Hat KVM, BIOS 0.5.1 01/01/2011 RIP: 0010:tcf_sample_act+0x9e/0x1e0 [act_sample] Code: 6a f1 85 c0 74 0d 80 3d 83 1a 00 00 00 0f 84 9c 00 00 00 4d 85 e4 0f 84 85 00 00 00 e8 9b d7 9c f1 44 8b 8b e0 00 00 00 31 d2 <41> f7 f1 85 d2 75 70 f6 85 83 00 00 00 10 48 8b 45 10 8b 88 08 01 RSP: 0018:ffffae320190ba30 EFLAGS: 00010246 RAX: 00000000b0677d21 RBX: ffff8af1ed9ec000 RCX: 0000000059a9fe49 RDX: 0000000000000000 RSI: 000000000c7e33b7 RDI: ffff8af23daa0af0 RBP: ffff8af1ee11b200 R08: 0000000074fcaf7e R09: 0000000000000000 R10: 0000000000000050 R11: ffffffffb3088680 R12: ffff8af232307f80 R13: 0000000000000003 R14: ffff8af1ed9ec000 R15: 0000000000000000 FS: 00007fe9c6d2f740(0000) GS:ffff8af23da80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fff6772f000 CR3: 00000000746a2004 CR4: 00000000001606e0 Call Trace: tcf_action_exec+0x7c/0x1c0 tcf_classify+0x57/0x160 __dev_queue_xmit+0x3dc/0xd10 ip_finish_output2+0x257/0x6d0 ip_output+0x75/0x280 ip_send_skb+0x15/0x40 raw_sendmsg+0xae3/0x1410 sock_sendmsg+0x36/0x40 __sys_sendto+0x10e/0x140 __x64_sys_sendto+0x24/0x30 do_syscall_64+0x60/0x210 entry_SYSCALL_64_after_hwframe+0x49/0xbe [...] Kernel panic - not syncing: Fatal exception in interrupt Add a TDC selftest to document that 'rate' is now being validated.

selftests: tc-testing: fix parsing of ife type

2019-02-27T09:08:56+00:00

[ Upstream commit 91fa038d9446b5bf5ea80822790af7dd9bcbb5a2 ] In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format specifier for the ife type changed from 0x%X to %#llX, causing systematic failures in the following TDC test cases: 7682 - Create valid ife encode action with mark and pass control ef47 - Create valid ife encode action with mark and pipe control df43 - Create valid ife encode action with mark and continue control e4cf - Create valid ife encode action with mark and drop control ccba - Create valid ife encode action with mark and reclassify control a1cf - Create valid ife encode action with mark and jump control cb3d - Create valid ife encode action with mark value at 32-bit maximum 95ed - Create valid ife encode action with prio and pass control aa17 - Create valid ife encode action with prio and pipe control 74c7 - Create valid ife encode action with prio and continue control 7a97 - Create valid ife encode action with prio and drop control f66b - Create valid ife encode action with prio and reclassify control 3056 - Create valid ife encode action with prio and jump control 7dd3 - Create valid ife encode action with prio value at 32-bit maximum 05bb - Create valid ife encode action with tcindex and pass control ce65 - Create valid ife encode action with tcindex and pipe control 09cd - Create valid ife encode action with tcindex and continue control 8eb5 - Create valid ife encode action with tcindex and continue control 451a - Create valid ife encode action with tcindex and drop control d76c - Create valid ife encode action with tcindex and reclassify control e731 - Create valid ife encode action with tcindex and jump control b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum 2a9c - Create valid ife encode action with mac src parameter cf5c - Create valid ife encode action with mac dst parameter 2353 - Create valid ife encode action with mac src and mac dst parameters 552c - Create valid ife encode action with mark and type parameters 0421 - Create valid ife encode action with prio and type parameters 4017 - Create valid ife encode action with tcindex and type parameters fac3 - Create valid ife encode action with index at 32-bit maximnum 7c25 - Create valid ife decode action with pass control dccb - Create valid ife decode action with pipe control 7bb9 - Create valid ife decode action with continue control d9ad - Create valid ife decode action with drop control 219f - Create valid ife decode action with reclassify control 8f44 - Create valid ife decode action with jump control b330 - Create ife encode action with cookie Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass both with old and new tc binaries. While at it, fix a small typo in test case fac3 ('maximnum'->'maximum'). Signed-off-by: Davide Caratti Acked-by: Stephen Hemminger Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

selftests: tc-testing: fix tunnel_key failure if dst_port is unspecified

2019-02-27T09:08:56+00:00

[ Upstream commit 5216bd77798e2ed773ecd45f3f368dcaec63e5dd ] After commit 1c25324caf82 ("net/sched: act_tunnel_key: Don't dump dst port if it wasn't set"), act_tunnel_key doesn't dump anymore the destination port, unless it was explicitly configured. This caused systematic failures in the following TDC test case: 7a88 - Add tunnel_key action with cookie parameter Avoid matching zero values of TCA_TUNNEL_KEY_ENC_DST_PORT to let the test pass again.

selftests: tc-testing: drop test on missing tunnel key id

2019-02-27T09:08:56+00:00

[ Upstream commit e413615502a3324daba038f529932ba9a5248af0 ] After merge of commit 80ef0f22ceda ("net/sched: act_tunnel_key: Allow key-less tunnels"), act_tunnel_key does not reject anymore requests to install 'set' rules where the key id is missing. Therefore, drop the following TDC testcase: ba4e - Add tunnel_key set action with missing mandatory id parameter because it's going to become a systematic fail as soon as userspace iproute2 will start supporting key-less tunnels.

tc-testing: add test-cases for numeric and invalid control action

2018-08-30T05:10:59+00:00

Only the police action allows us to specify an arbitrary numeric value for the control action. This change introduces an explicit test case for the above feature and then leverage it for testing the kernel behavior for invalid control actions (reject).

tc: Update README and add config

2018-08-11T19:20:59+00:00
