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. 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).

2013-09-15exec: keep track of the range where executable segments are mappedJustus Winter
Keep track of the range where executable segments are mapped into memory and hand that information over to the proc server. * exec/priv.h (struct execdata): Add {start,end}_code. * exec/exec.c (prepare): Initialize {start,end}_code. (load_section): Update {start,end}_code. (do_exec): Use proc_set_code to hand {start,end}_code to the proc server.
2013-08-29exec: remove the BFD codeJustus Winter
This commit removes the parts of the exec server that were once using the Binary File Descriptor library. As I understand it, the BFD code stopped working because it uses stdio streams and the glue code for that has never been ported to libio. The code has been #ifdefed out ever since. It may or may not work in its current state, so it is removed. If someone is interested, it can always be recovered from the version control system. * exec/exec.c: Remove all BFD related code. * exec/priv.h: Likewise. * TODO: Remove the corresponding item.
2013-08-28exec: Remove #ifdef 0-out code for user specified exec servers.Justus Winter
This code was meant to allow the user to specify alternative exec servers using an environment variable. The Hurd uses the file system as namespace for server lookups, so the proper way to use one's own exec server seems to be the remap translator. * exec/exec.c (S_exec_exec): Remove unused code.
