* Linux: Add support for chrooted renderers.agl@chromium.org2009-06-041-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://code.google.com/p/chromium/wiki/LinuxSandboxIPC Without filesystem access from the renderers, we need another way of dealing with fontconfig and font loading. This add support for: * An "SBX_D" environment variable in the renderers which is used to signal the end of dynamic linking so that the chroot can be enforced. * A sandbox_host process, running outside the sandbox, to deal with fontconfig requests from the renderers. See the wiki page for the reasoning behind making it a separate process. * A new, custom SkFontHost for Skia. Because this is Chrome specific, it will live outside the upstream Skia tree. This FontHost can be configured either to drive fontconfig directly (for the browser process and for any unsandboxed renderers) or to use an IPC system. Since the same SkFontHost has to be linked into both the browser and renderer (they are the same binary), this switch has to be made at run time. Sandbox IPC calls are rare (a couple of dozen at page load time) and add about 50us of overhead for each call. http://codereview.chromium.org/112074 BUG=8081 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@17575 0039d316-1c4b-4281-b951-d872f2087c98

* POSIX: Add a macro for handling EINTR.agl@chromium.org2009-05-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On POSIX systems, system calls can be interrupted by signals. In this case, they'll return EINTR, indicating that the system call needs to be restarted. (The situation is a little more complicated than this with SA_RESTART, but you can read man 7 signal if you like.) The short of it is that you need to catch EINTR and restart the call for these system calls: * read, readv, write, writev, ioctl * open() when dealing with a fifo * wait* * Anything socket based (send*, recv*, connect, accept etc) * flock and lock control with fcntl * mq_ functions which can block * futex * sem_wait (and timed wait) * pause, sigsuspend, sigtimedwait, sigwaitinfo * poll, epoll_wait, select and 'p' versions of the same * msgrcv, msgsnd, semop, semtimedop * close (although, on Linux, EINTR won't happen here) * any sleep functions (careful, you need to handle this are restart with different arguments) We've been a little sloppy with this until now. This patch adds a macro for dealing with this and corrects every case of these system calls (that I found). The macro is HANDLE_EINTR in base/eintr_wrapper.h. It's safe to include on Windows and is a no-op there. On POSIX, it uses GCC magic to return the correct type based on the expression and restarts the system call if it throws EINTR. And you can use it like: HANDLE_EINTR(close(fd)); Or: ssize_t bytes_read = HANDLE_EINTR(read(fd, buffer, len)); *BEWARE* that it will evaluate the argument multiple times, so this is not safe: HANDLE_EINTR(close(FireMissiles())); http://groups.google.com/group/chromium-dev/browse_thread/thread/41a35b2a457d73a0 http://codereview.chromium.org/100225 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@15102 0039d316-1c4b-4281-b951-d872f2087c98
* POSIX: Add code for shuffling file descriptors.agl@chromium.org2009-04-301-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | When forking a child process, one often wants to move existing file descriptors to well known locations (stdout, stderr etc). However, this is a process bedeviled with corner cases. Consider the case where you open two file descriptors, get assigned fds 1 and 0 for them and wish to shuffle them so that they end up in slots 0 and 1. Our current code fails in this case. We also have a problem where we're currently trying to mark file descriptors as close-on-exec rather than closing them in the child process. This is inherently broken in a multithreaded process where another thread can open a file descriptor and race the loop which is trying to mark them. Thus, on Linux we switch to close-after-fork where we known that no other threads exist in the process. On Mac, the code is sufficiently different that this simple fix isn't applicable and one of the Mac folks will need to take a look. http://codereview.chromium.org/100127 BUG=11174 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@14978 0039d316-1c4b-4281-b951-d872f2087c98

One explicit goal of this change is to *not* deal with the string/wstring issues at the API on POSIX; the functions are the same as before, which means they remain as broken as before.
