On CentOS 7 (glibc-2.17-326.el7_9.3.x86_64), ld-2.17.so is mapped like following:
7f830b42c000-7f830b44e000 r-xp 00000000 08:04 202220966 /usr/lib64/ld-2.17.so However SA maps it as following. Base address is correct, but end address is different from "maps". libsaproc DEBUG: /usr/lib64/ld-2.17.so [0] 0x7f830b42c000-0x7f830b62c000: base = 0x7f830b42c000, vaddr = 0x0, memsz = 0x21960, filesz = 0x21960 We fixed calculation logic in [JDK-8377395](https://bugs.openjdk.org/browse/JDK-8377395) to align end address to align `p_align` in ELF header, but the logic seems to be incorrect (note that the calculation is working as expected). Linux Kernel ([fs/binfmt_elf.c](https://github.com/torvalds/linux/blob/v6.19/fs/binfmt_elf.c#L414)) aligns end address with page size, not `p_align`. So SA might need to follow it. Otherwise address it might happen address confliction what we saw in [JDK-8377395](https://bugs.openjdk.org/browse/JDK-8377395). ------------- Commit messages: - Align with page size for end address Changes: https://git.openjdk.org/jdk/pull/30154/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30154&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8379454 Stats: 2 lines in 1 file changed: 1 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/30154.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30154/head:pull/30154 PR: https://git.openjdk.org/jdk/pull/30154
