Eigler +Date: Mon Jul 27 07:58:30 2020 -0400 + + PR25568 / RHBZ1857749: buildid/uprobes/inode rework, task_finder etc. side + + During work on a new stress tests for build-id based probes (coming in + next commit), it was found that the task_finder2 logic for buildid + verification didn't, well, work, because it was never run (due to an + erroneous pathlen conditional), and couldn't be safely run where it + was (because it was under spinlock but would have done + access_process_vm). Reworked the relevant bits of task_finder2 to + perform build-id verification for processes later - during the quiesce + callback periods. (Buildid verification for solibs is already done + in the task_finder2 consumer uprobes-inode.c.) + + Testing with sdt_misc indicated a case where a preexisting process + (with solib sdt.h semaphores) was being attached to by a new stap + binary. task_finder2's enumeration of the preexising processes' + memory map segments violated assumptions by recent code related to + tracking in stapiu_process[] lists. (It did not mirror the temporal + ld.so mmap sequence.) Changed this tracking to use the inode* as the + key, and stop trying to track mapping lengths, to make positive + matches and eliminate duplicate stapiu_process[] entries for the same + (process,solib) permutation. Reworked stapiu_process[] accumulation + generally to move to the two immediate task_finder callbacks, out of + stapiu_change_plus(). + + Added lots of commentary and diagnostics throughout. stap + -DDEBUG_UPROBES give meaningful info about uprobes & sdt semaphores; + with -DDEBUG_TASK_FINDER, more but not overwhelming relevant info + appears. + +diff --git a/runtime/linux/task_finder2.c b/runtime/linux/task_finder2.c +index 9777efb..8b8057a 100644 +--- a/runtime/linux/task_finder2.c ++++ b/runtime/linux/task_finder2.c +@@ -652,8 +652,8 @@ __verify_build_id(struct task_struct *tsk, unsigned long addr, + tsk_build_id[build_id_len] = '\0'; + + if (strcmp(build_id, tsk_build_id)) { +- dbug_task(2, "target build-id not matched: [%s] != [%s]\n", +- build_id, tsk_build_id); ++ dbug_task(2, "target build-id not matched: [%s] @ 0x%lx != [%s]\n", ++ build_id, addr, tsk_build_id); + return false; + } + +@@ -884,16 +884,9 @@ __stp_utrace_attach_match_filename(struct task_struct *tsk, + // procname/build-id and match an "all thread" probe. + if (tgt == NULL) + continue; +- /* buildid-based target */ +- else if (tgt->build_id_len > 0 && tgt->procname > 0 +- && !__verify_build_id(tsk, +- tgt->build_id_vaddr, +- tgt->build_id, +- tgt->build_id_len)) +- { +- continue; +- } +- else if (tgt->build_id_len == 0 && tgt->pathlen > 0 ++ /* buildid-based target ... gets checked in __stp_tf_quiesce_worker */ ++ /* procname-based target */ ++ else if (tgt->pathlen > 0 + && (tgt->pathlen != filelen + || strcmp(tgt->procname, filename) != 0)) + { +@@ -1341,6 +1334,34 @@ __stp_tf_quiesce_worker(struct task_work *work) + return; + } + ++ /* If we had a build-id based executable probe (so we have a ++ * tgt->build_id) set, we could not check it back in ++ * __stp_utrace_attach_* because we can't do sleepy ++ * access_process_vm() calls from there.
