* Revert r267233 for now. PIE support needs to be reworked.Bryan Drewery2014-08-191-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other build-only utility libraries. 2. Another 40% is fixed by generating _pic.a variants of various libraries. 3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases. 4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed. We likely do want to enable PIE by default (opt-out) for non-tree consumers (such as ports). For in-tree though we probably want to only enable PIE (opt-in) for common attack targets such as remote service daemons and setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled. Reported by: kib Notes: svn path=/head/; revision=270168

* sh: Mask off shift distance (<< and >>) in arithmetic.Jilles Tjoelker2014-08-153-2/+44
| | | | | | | | | | | | | | In C, shift distances equal to or larger than the number of bits in the operand result in undefined behaviour. As part of eliminating undefined behaviour in arithmetic, mask off the distance like Java and JavaScript specify and C on x86 usually does. Assumption: conversion from unsigned to signed retains the two's complement bits. Assumption: uintmax_t has no padding bits. Notes: svn path=/head/; revision=270029

* Correct the problems with the ptrace(2) making the debuggee an orphan.Konstantin Belousov2014-08-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One problem is inferior(9) looping due to the process tree becoming a graph instead of tree if the parent is traced by child. Another issue is due to the use of p_oppid to restore the original parent/child relationship, because real parent could already exited and its pid reused (noted by mjg). Add the function proc_realparent(9), which calculates the parent for given process. It uses the flag P_TREE_FIRST_ORPHAN to detect the head element of the p_orphan list and than stepping back to its container to find the parent process. If the parent has already exited, the init(8) is returned. Move the P_ORPHAN and the new helper flag from the p_flag* to new p_treeflag field of struct proc, which is protected by proctree lock instead of proc lock, since the orphans relationship is managed under the proctree_lock already. The remaining uses of p_oppid in ptrace(PT_DETACH) and process reapping are replaced by proc_realparent(9).

* sh: Correctly handle positional parameters beyond INT_MAX on 64-bit systems.Jilles Tjoelker2014-07-123-2/+19
| | | | | | | | | | | | | | | | Currently, there can be no more than INT_MAX positional parameters. Make sure to treat all higher ones as unset to avoid incorrect results and crashes. On 64-bit systems, our atoi() takes the low 32 bits of the strtol() and sign-extends them. On 32-bit systems, the call to atoi() returned INT_MAX for too high values and there is not enough address space for so many positional parameters, so there was no issue.

Such positional parameters are checked for being unset and/or null correctly, but their value is incorrectly expanded. Notes: svn path=/head/; revision=268436

* rm -rf can fail sometimes with an error from fts_read. Make it honorWarner Losh2014-07-071-1/+1
| | | | | | | | | | | | | | | | fflag to ignore fts_read errors, but stop deleting from that directory because no further progress can be made. When building a kernel with a high -j value on a high core count machine, during the cleanobj phase we can wind up doing multiple rm -rf at the same time for modules that have subdirectories. This exposed this race (sometimes) as fts_read can return an error if the directory is removed by another rm -rf. Since the intent of the -f flag was to ignore errors, even if this was a bug in fts_read, we should ignore the error like we've been instructed to do. Notes: svn path=/head/; revision=268376
