2013-09-15exec: remove support for transparently ungziping executablesJustus Winter
Remove support for transparently ungziping executables from the exec server. The code in question makes the exec server unnecessarily complex and since the exec server is an essential process, crashing it makes /hurd/init crash the whole system. Since the gzip code is not thread-safe, all access to it is serialized, so there is a trivial way for one user to delay another users gzipped executables for some unspecified time. This can be accomplished by padding any program with easily compressed data, zipping it and executing it. Using such a program as an passive translator and then triggering its execution by the filesystem translator also stalls any requests to that filesystem (observed using the libdiskfs-based ext2fs). Since compressed executables cannot be mapped into the memory, they have to be uncompressed into allocated memory first. This is slower and any user with access to the exec server can make it allocate arbitrary amounts of memory. If the Hurd had proper memory accounting, this would probably be a way around it. So the compression support in exec seemingly creates various issues for little value, at least with the abundance of nonvolatile memory available today. * exec/Makefile: Remove gzip related files. * exec/exec.c: Remove anything #ifdef GZIPped. * exec/unzip.c: Move to libstore. * exec/crypt.h: Likewise. * exec/gzip.h: Likewise. * exec/inflate.c: Likewise. * exec/tailor.h: Likewise. * exec/util.c: Likewise. * libstore/Makefile: Remove the vpath magic for looking up the zip stuff.

Remove support for transparently unbzip2ing executables from the exec server. The code in question makes the exec server unnecessarily complex and since the exec server is an essential process, crashing it makes /hurd/init crash the whole system. Since the bzip2 code is not thread-safe, all access to it is serialized, so there is a trivial way for one user to delay another users bzip2ed executables for some unspecified time.

2013-09-15trans: add mtab translatorJustus Winter
The mtab translator provides an mtab file that is dynamically created on demand. It is populated with information about active translators bound below the given path that is accumulated by traversing the translator tree. It can also be invoked as normal program that prints the requested information to stdout. * trans/mtab.c: New file. * trans/Makefile: Build mtab.
2013-09-15hurd: add fsys_get_sourceJustus Winter
Return information about the source of the receiving filesystem. If the concept of a source is applicable, SOURCE should refer to the source of the receiving translator and should be a description considered appropriate in the context of the translator. For example for the case of block device based filesystems, SOURCE should be the file name of the underlying block device. * hurd/fsys.defs: Add fsys_get_source. * hurd/fsys_reply.defs: Add fsys_get_source.
