2016-08-19syscall.c: Redefine IFLA_* enumsMichal Privoznik
In 9c37146782 I've tried to fix a broken build with older linux-headers. However, I didn't do it properly. The solution implemented here is to grab the enums that caused the problem initially, and rename their values so that they are "QEMU_" prefixed. In order to guarantee matching values with actual enums from linux-headers, the enums are seeded with starting values from the original enums.

2016-08-16linux-user: Fix llseek with high bit of offset_low setPeter Maydell
The llseek syscall takes two 32-bit arguments, offset_high and offset_low, which must be combined to form a single 64-bit offset. Unfortunately we were combining them with (uint64_t)arg2 << 32) | arg3 and arg3 is a signed type; this meant that when promoting arg3 to a 64-bit type it would be sign-extended. The effect was that if the offset happened to have bit 31 set then this bit would get sign-extended into all of bits 63..32. Explicitly cast arg3 to abi_ulong to avoid the erroneous sign extension.

2016-08-16syscall.c: Fix build with older linux-headersMichal Privoznik
In c5dff280 we tried to make us understand netlink messages more. So we've added a code that does some translation. However, the code assumed linux-headers to be at least version 4.4 of it because most of the symbols there (if not all of them) were added in just that release. This, however, breaks build on systems with older versions of the package.

2016-08-04linux-user: Handle brk() attempts with very large sizesPeter Maydell
In do_brk(), we were inadvertently truncating the size of a requested brk() from the guest by putting it into an 'int' variable. This meant that we would incorrectly report success back to the guest rather than a failed allocation, typically resulting in the guest then segfaulting. Use abi_ulong instead. This fixes a crash in the '31370.cc' test in the gcc libstdc++ test suite (the test case starts by trying to allocate a very large size and reduces the size until the allocation succeeds).

2016-08-04linux-user: Fix target_semid_ds structure definitionPeter Maydell
The target_semid_ds structure is not correct for all architectures: the padding fields should only exist for: * 32-bit ABIs * x86 It is also misnamed, since it is following the kernel semid64_ds structure (QEMU doesn't support the legacy semid_ds structure at all). Rename the struct, provide a correct generic definition and allow the oddball x86 architecture to provide its own version. This fixes broken SYSV semaphores for all our 64-bit architectures except x86 and ppc. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

Use g_strlcpy() rather than strcpy() to copy the uname string into the structure we return to the guest for the uname syscall.

2016-08-04linux-user: Fix memchr() argument in open_self_cmdline()Peter Maydell
In open_self_cmdline() we look for a 0 in the buffer we read from /prc/self/cmdline. We were incorrectly passing the length of our buf[] array to memchr() as the length to search, rather than the number of bytes we actually read into it, which could be shorter. This was spotted by Coverity (because it could result in our trying to pass a negative length argument to write()).

2016-07-19linux-user: Handle short lengths in host_to_target_sockaddr()Peter Maydell
If userspace specifies a short buffer for a target sockaddr, the kernel will only copy in as much as it has space for (or none at all if the length is zero) -- see the kernel move_addr_to_user() function. Mimic this in QEMU's host_to_target_sockaddr() routine. In particular, this fixes a segfault running the LTP recvfrom01 test, where the guest makes a recvfrom() call with a bad buffer pointer and other parameters which cause the kernel to set the addrlen to zero; because we did not skip the attempt to swap the sa_family field we segfaulted on the bad address.

2016-07-19linux-user: Forget about synchronous signal once it is deliveredPeter Maydell
Commit 655ed67c2a248cf which switched synchronous signals to benig recorded in ts->sync_signal rather than in a queue with every other signal had a bug: we failed to clear the flag indicating that a synchronous signal was pending when we delivered it. This meant that we would take the signal again and again every time the guest made a syscall. (This is a bug introduced in my refactoring of Timothy Baldwin's original code.) Fix this by passing in the struct emulated_sigtable* to handle_pending_signal(), so that we clear the pending flag in the ts->sync_signal struct when handling a synchronous signal.

The LOOP_GET_STATUS and LOOP_GET_STATUS64 ioctls were incorrectly defined as IOC_W rather than IOC_R, which meant we weren't correctly copying the information back from the kernel to the guest. The loop_info64 structure definition was also missing a member and using the wrong type for several 32-bit fields. In particular, this meant that "kpartx -d image.img" didn't work and "losetup -a" behaved strangely. Correct the ioctl type definitions.

The BLKSSZGET ioctl takes an argument which is a pointer to an int. We were incorrectly declaring it to take a pointer to a long, which meant that we would incorrectly write to memory which we should not if the guest is a 64-bit architecture.

2016-07-19linux-user: fix netlink memory corruptionLaurent Vivier
Netlink is byte-swapping data in the guest memory (it's bad). It's ok when the data come from the host as they are generated by the host. But it doesn't work when data come from the guest: the guest can try to reuse these data whereas they have been byte-swapped. This is what happens in glibc: glibc generates a sequence number in nlh.nlmsg_seq and calls sendto() with this nlh. In sendto(), we byte-swap nlmsg.seq. Later, after the recvmsg(), glibc compares nlh.nlmsg_seq with sequence number given in return, and of course it fails (hangs), because nlh.nlmsg_seq is not valid anymore. The involved code in glibc is: sysdeps/unix/sysv/linux/check_pf.c:make_request() ... req.nlh.nlmsg_seq = time (NULL); ... if (TEMP_FAILURE_RETRY (__sendto (fd, (void *) &req, sizeof (req), 0, (struct sockaddr *) &nladdr, sizeof (nladdr))) < 0) <here req.nlh.nlmsg_seq has been byte-swapped> ... do { ... ssize_t read_len = TEMP_FAILURE_RETRY (__recvmsg (fd, &msg, 0)); ... struct nlmsghdr *nlmh; for (nlmh = (struct nlmsghdr *) buf; NLMSG_OK (nlmh, (size_t) read_len); nlmh = (struct nlmsghdr *) NLMSG_NEXT (nlmh, read_len)) { <we compare nlmh->nlmsg_seq with corrupted req.nlh.nlmsg_seq> if (nladdr.nl_pid != 0 || (pid_t) nlmh->nlmsg_pid != pid || nlmh->nlmsg_seq != req.nlh.nlmsg_seq) continue; ... else if (nlmh->nlmsg_type == NLMSG_DONE) /* We found the end, leave the loop. */ done = true; } } while (! done); As we have a continue on "nlmh->nlmsg_seq != req.nlh.nlmsg_seq", "done" cannot be set to "true" and we have an infinite loop. It's why commands like "apt-get update" or "dnf update hangs". Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2016-06-29target-*: Don't redefine cpu_exec()Peter Crosthwaite
This function needs to be converted to QOM hook and virtualised for multi-arch. This rename interferes, as cpu-qom will not have access to the renaming causing name divergence. This rename doesn't really do anything anyway so just delete it.

2016-06-28trace: [*-user] Add events to trace guest syscalls in syscall emulation modeLluís Vilanova
Adds two events to trace syscalls in syscall emulation mode (*-user): * guest_user_syscall: Emitted before the syscall is emulated; contains the syscall number and arguments. * guest_user_syscall_ret: Emitted after the syscall is emulated; contains the syscall number and return value.
