* Make .note.android.ident section type SH_NOTEColin Cross2015-02-121-48/+0
| | | | | | | | | | | | | | | | | | The .note.android.ident section is only used by GDB, which doesn't care what section type the section is, but it would be convenient for readelf -n to be able to find the section too. The old way of getting the .note.android.ident section to be of type SH_NOTE involved compiling from .c to .s using gcc, running sed to change progbits to note, and then compiling from .s to .o using gcc. Since crtbrand.c only contains a section containing data, a crtbrand.S can be checked in that will compile on all platforms, avoiding the need for sed. Also add crtbrand.o to crtbegin_so.o so that libraries also get the note, and to the crt workaround in arm libc.so. Change-Id: Ica71942a6af4553b56978ceaa288b3f4c15ebfa2
* Remove no-op sed step when compiling crtbrand.oColin Cross2015-02-111-15/+0
| | | | | | | | | | | | crtbrand.c was compiled to a .s file, run through a sed script to translate a %progbits to %note, and the compiled to .o. However, when the sed command was copied from the original source it was not updated to use the new name of the section (.note.ABI-tag to .note.android.ident), so it didn't modify the file. Since the section has been generated with type %progbits instead of %note for two years, just delete the whole sed step. Change-Id: Id78582e9b43b628afec4eed22a088283132f0742

* | | Ensure raw fchmod/fchmodat syscalls are hidden.Nick Kralevich2015-02-032-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In https://android-review.googlesource.com/#/c/127908/5/libc/SYSCALLS.TXT@116 Elliott said: for LP64 these will be hidden. for LP32 we were cowards and left them all public for compatibility (though i don't think we ever dremeled to see whether it was needed). we don't have an easy way to recognize additions, though, so we can't prevent adding new turds. Add a mechanism to prevent the adding of new turds, and use that mechanism on the fchmod/fchmodat system calls. Bug: 19233951 Change-Id: I98f98345970b631a379f348df57858f9fc3d57c0

| * | | Add fchmodat(AT_SYMLINK_NOFOLLOW) and fchmod O_PATH supportNick Kralevich2015-02-022-0/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many libc functions have an option to not follow symbolic links. This is useful to avoid security sensitive code from inadvertantly following attacker supplied symlinks and taking inappropriate action on files it shouldn't. For example, open() has O_NOFOLLOW, chown() has lchown(), stat() has lstat(), etc. There is no such equivalent function for chmod(), such as lchmod(). To address this, POSIX introduced fchmodat(AT_SYMLINK_NOFOLLOW), which is intended to provide a way to perform a chmod operation which doesn't follow symlinks. Currently, the Linux kernel doesn't implement AT_SYMLINK_NOFOLLOW. In GLIBC, attempting to use the AT_SYMLINK_NOFOLLOW flag causes fchmodat to return ENOTSUP. Details are in "man fchmodat". Bionic currently differs from GLIBC in that AT_SYMLINK_NOFOLLOW is silently ignored and treated as if the flag wasn't present. This patch provides a userspace implementation of AT_SYMLINK_NOFOLLOW for bionic. Using open(O_PATH | O_NOFOLLOW), we can provide a way to atomically change the permissions on files without worrying about race conditions. As part of this change, we add support for fchmod on O_PATH file descriptors, because it's relatively straight forward and could be useful in the future. The basic idea behind this implementation comes from https://sourceware.org/bugzilla/show_bug.cgi?id=14578 , specifically comment #10. Change-Id: I1eba0cdb2c509d9193ceecf28f13118188a3cfa7

* Split the shared group data from the shared passwd data.Elliott Hughes2014-12-181-35/+47
| | | | | | | | | | | | | | Found by the toybox id(1) which calls both getpwuid(3) and getgrgid(3) before looking at either result. The use of a shared buffer in this code meant that even on a single thread, the data for any of the passwd functions would be clobbered by the data for any of the group functions (or vice versa). This might seem like an insufficient fix, but POSIX explicitly says (for getpwnam) that the result "might be overwritten by a subsequent call to getpwent(), getpwnam(), or getpwuid()" and likewise for other members of that group, plus equivalent text for the group-related functions.
