This can be tested by giving the following test program a # filename in an AFS directory: # # #include <stdio.h> # #include <stdlib.h> # #include <unistd.h> # #include <fcntl.h> # #include <sys/mman.h> # int main(int argc, char argv[]) # { # char p; # int fd; # if (argc != 2) { # fprintf(stderr, # "Format: test-trunc-mmap <file>\n"); # exit(2); # } # fd = open(argv[1], O_RDWR \| O_CREAT \| O_TRUNC); # if (fd < 0) { # perror(argv[1]); # exit(1); # } # if (ftruncate(fd, 0x140008) == -1) { # perror("ftruncate"); # exit(1); # } # p = mmap(NULL, 4096, PROT_READ \| PROT_WRITE, # MAP_SHARED, fd, 0); # if (p == MAP_FAILED) { # perror("mmap"); # exit(1); # } # p[0] = 'a'; # if (munmap(p, 4096) < 0) { # perror("munmap"); # exit(1); # } # if (close(fd) < 0) { # perror("close"); # exit(1); # } # exit(0); # } # # Fixes: 31143d5d515e ("AFS: implement basic file write support") # Reported-by: Jonathan Billings <jsbillin@umich.edu> # Tested-by: Jonathan Billings <jsbillin@umich.edu> # Signed-off-by: David Howells <dhowells@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 8c7ae38d1ce12a0eaeba655df8562552b3596c7f # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_malta_defconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- malta_defconfig # make -s -j 8 ARCH=mips O=/kisskb/build/linus_malta_defconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/vdso/Makefile:39: MIPS VDSO requires binutils >= 2.25 <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] /kisskb/src/arch/mips/vdso/Makefile:39: MIPS VDSO requires binutils >= 2.25 /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:187:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:140:32: warning: 'levelspread[<U 820>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:88:6: note: 'levelspread[<U 820>]' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2594:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/bridge/br_netlink.c: In function 'br_afspec.isra.21': /kisskb/src/net/bridge/br_netlink.c:652:7: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:337:21: note: 'pdeo' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1842:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1755:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here /kisskb/src/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1581:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1538:6: note: 'pwr_level_cisco' was declared here /kisskb/src/fs/fs_parser.c: In function 'fs_validate_description': /kisskb/src/fs/fs_parser.c:413:6: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'int' [-Wformat] Completed OK # rm -rf /kisskb/build/linus_malta_defconfig_mips # Build took: 0:03:20.720351
