2023-03-13win32: replace closesocket() with close() wrapperMarc-André Lureau
Use a close() wrapper instead, so that we don't need to worry about closesocket() vs close() anymore, let's hope. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Stefan Berger <stefanb@linux.ibm.com> Message-Id: <20230221124802.4103554-17-marcandre.lureau@redhat.com>

2023-03-13win32: avoid mixing SOCKET and file descriptor spaceMarc-André Lureau
Until now, a win32 SOCKET handle is often cast to an int file descriptor, as this is what other OS use for sockets. When necessary, QEMU eventually queries whether it's a socket with the help of fd_is_socket(). However, there is no guarantee of conflict between the fd and SOCKET space. Such conflict would have surprising consequences, we shouldn't mix them. Also, it is often forgotten that SOCKET must be closed with closesocket(), and not close(). Instead, let's make the win32 socket wrapper functions return and take a file descriptor, and let util/ wrappers do the fd/SOCKET conversion as necessary. A bit of adaptation is necessary in io/ as well. Unfortunately, we can't drop closesocket() usage, despite _open_osfhandle() documentation claiming transfer of ownership, testing shows bad behaviour if you forget to call closesocket().

2023-03-13slirp: unregister the win32 SOCKETMarc-André Lureau
Presumably, this is what should happen when the SOCKET is to be removed.

Use TT_TRAP. For sparc32, 0x88 is the "Slowaris" system call, currently BAD_TRAP in the kernel's ttable_32.S. For sparc64, 0x110 is tl0_linux32, the sparc32 trap, now folded into the TARGET_ABI32 case via TT_TRAP. For sparc64, there does still exist trap 0x111 as tl0_oldlinux64, which was replaced by 0x16d as tl0_linux64 in 1998. Since no one has noticed, don't bother implementing it now.

2023-03-10linux-user: Emulate CLONE_PIDFD flag in clone()Helge Deller
Add emulation for the CLONE_PIDFD flag of the clone() syscall. This flag was added in Linux kernel 5.2. Successfully tested on a x86-64 Linux host with hppa-linux target. Can be verified by running the testsuite of the qcoro debian package, which breaks hard and kills the currently logged-in user without this patch.

msync() uses the flags MS_ASYNC, MS_INVALIDATE and MS_SYNC, which differ between platforms, specifcally on alpha and hppa.

2023-03-10linux-user: handle netlink flag NLA_F_NESTEDMathis Marion
Newer kernel versions require this flag to be present contrary to older ones. Depending on the libnl version it is added or not. Typically when using rtnl_link_inet6_set_addr_gen_mode, the netlink packet generated may contain the following attribute: with libnl 3.4 {nla_len=16, nla_type=IFLA_AF_SPEC}, [ {nla_len=12, nla_type=AF_INET6}, [{nla_len=5, nla_type=IFLA_INET6_ADDR_GEN_MODE}, IN6_ADDR_GEN_MODE_NONE] ] with libnl 3.7 {nla_len=16, nla_type=NLA_F_NESTED|IFLA_AF_SPEC}, [ {nla_len=12, nla_type=NLA_F_NESTED|AF_INET6}, [{nla_len=5, nla_type=IFLA_INET6_ADDR_GEN_MODE}, IN6_ADDR_GEN_MODE_NONE]] ] Masking the type is likely needed in other places. Only the above cases are implemented in this patch.

Add a new function print_raw_param64() to print 64-bit values in the same way as print_raw_param(). This prevents that qemu_log() is used to work around the problem that print_raw_param() can only print 32-bit values when compiled for 32-bit targets.

2023-03-10linux-user: Fix brk() to release pagesHelge Deller
The current brk() implementation does not de-allocate pages if a lower address is given compared to earlier brk() calls. But according to the manpage, brk() shall deallocate memory in this case and currently it breaks a real-world application, specifically building the debian gcl package in qemu-user. Fix this issue by reworking the qemu brk() implementation. Tested with the C-code testcase included in qemu commit 4d1de87c750, and by building debian package of gcl in a hppa-linux guest on a x86-64 host.

2023-03-10linux-user: Fix unaligned memory access in prlimit64 syscallIlya Leoshkevich
target_rlimit64 contains uint64_t fields, so it's 8-byte aligned on some hosts, while some guests may align their respective type on a 4-byte boundary. This may lead to an unaligned access, which is an UB. Fix by defining the fields as abi_ullong. This makes the host alignment match that of the guest, and lets the compiler know that it should emit code that can deal with the guest alignment. While at it, also use __get_user() and __put_user() instead of tswap64().

2023-03-10linux-user: Fix access to /proc/self/exeHelge Deller
When accsssing /proc/self/exe from a userspace program, linux-user tries to resolve the name via realpath(), which may fail if the process changed the working directory in the meantime. An example: - a userspace program ist started with ./testprogram - the program runs chdir("/tmp") - then the program calls readlink("/proc/self/exe") - linux-user tries to run realpath("./testprogram") which fails because ./testprogram isn't in /tmp - readlink() will return -ENOENT back to the program Avoid this issue by resolving the full path name of the started process at startup of linux-user and store it in real_exec_path[]. This then simplifies the emulation of readlink() and readlinkat() as well, because they can simply copy the path string to userspace. I noticed this bug because the testsuite of the debian package "pandoc" failed on linux-user while it succeeded on real hardware. The full log is here: https://buildd.debian.org/status/fetch.php?pkg=pandoc&arch=hppa&ver=2.17.1.1-1.1%2Bb1&stamp=1670153210&raw=0 Signed-off-by: Helge Deller <deller@gmx.de> Reviewed-by: Laurent Vivier <laurent@vivier.eu> Message-Id: <20221205113825.20615-1-deller@gmx.de> Signed-off-by: Laurent Vivier <laurent@vivier.eu>
