  "message": "fs,proc: Respect FMODE_WRITE when opening /proc/pid/fd/N\n\nThis patch does this:\n\n    # (echo asdf \u003e/proc/self/fd/3) 3\u003c/dev/null\n    bash: /proc/self/fd/3: Permission denied\n\nI\u0027m not confident that my use of nd-\u003eflags is correct.  I\u0027m also not\nconfident that this hooks in to path lookup in the right place.\n\nIt is not complete.  It doesn\u0027t handle FMODE_READ.  It also doesn\u0027t\nhandle FMODE_EXEC or FMODE_PATH, but the desired semantics there are\nless clear.  For example, this should probably continue to work:\n\n    (/proc/self/fd/3 Hello) 3\u003c/bin/echo\n\nThis patch does not do anything to /proc/self/exe.  It probably should.\n\nThis may break userspace.  If so, I would argue that anything broken\nby it is either an actual exploit or is so broken that it doesn\u0027t\ndeserve to continue working.  If it breaks something important, then\nmaybe it will need a sysctl.\n\nSigned-off-by: Andy Lutomirski \u003cluto@amacapital.net\u003e\n",
