Newer\ndistributions (using glibc 2.3.3 or later) can turn this option off. Turning\nit off is also recommended for security reasons: attackers cannot use the\npredictable high-mapped VDSO page as syscall trampoline anymore.\n\nThere is a new vdso\u003d[0|1] boot option as well, and a runtime\n/proc/sys/vm/vdso_enabled sysctl switch, that allows the VDSO to be turned\non/off.\n\n(This version of the VDSO-randomization patch also has working ELF\ncoredumping, the previous patch crashed in the coredumping code.)\n\nThis code is a combined work of the exec-shield VDSO randomization\ncode and Gerd Hoffmann\u0027s hypervisor-centric VDSO patch.

The chroot check was\nasking a question about the visibility of files to the calling process and\nit was actually checking the destination process, and not the files\nthemselves. That test was clearly bogus.\n\nIn my first pass through I simply fixed the test to check the visibility of\nthe files themselves. That naive approach to fixing the permissions was\ntoo strict and resulted in cases where a task could not even see all of\nit\u0027s file descriptors.\n\nWhat has disturbed me about relaxing this check is that file descriptors\nare per-process private things, and they are occasionaly used a user space\ncapability tokens. Looking a little farther into the symlink path on /proc\nI did find userid checks and a check for capability (CAP_DAC_OVERRIDE) so\nthere were permissions checking this.\n\nBut I was still concerned about privacy. Besides /proc there is only one\nother way to find out this kind of information, and that is ptrace. ptrace\nhas been around for a long time and it has a well established security\nmodel.\n\nSo after thinking about it I finally realized that the permission checks\nthat make sense are the permission checks applied to ptrace_attach. The\nchecks are simple per process, and won\u0027t cause nasty surprises for people\ncoming from less capable unices.\n\nUnfortunately there is one case that the current ptrace_attach test does\nnot cover: Zombies and kernel threads. Single stepping those kinds of\nprocesses is impossible. Being able to see which file descriptors are open\non these tasks is important to lsof, fuser and friends. So for these\nspecial processes I made the rule you can\u0027t find out unless you have\nCAP_SYS_PTRACE.\n\nThese proc permission checks should now conform to the principle of least\nsurprise.

It was an\nunsophisticated time and no one was worried about functions full of FIXMES in\na stable kernel. As time passed the function became sacred and was enshrined\nin the shrine of how things have always been. The fixes came in but only to\nkeep the function working no one really remembering or documenting why we did\nthings that way.\n\nThe intent and the functionality make a lot of sense. Don\u0027t let /proc be an\naccess point for files a process can see no other way. The implementation\nhowever is completely wrong.\n\nWe are currently checking the root directories of the two processes, we are\nnot checking the actual file descriptors themselves.\n\nWe are strangely checking with a permission method instead of just when we use\nthe data.\n\nThis patch fixes the logic to actually check the file descriptors and make a\nnote that implementing a permission method for this part of /proc almost\ncertainly indicates a bug in the reasoning.\n\nSigned-off-by: Eric W.
