Opening a file requires another operation: allocation of a file structure (this is the kernel-side implementation of file descriptors). The freshly allocated file structure is initialized with a pointer to the dentry and a set of file operation member functions. These are taken from the inode da...
This invariant exists (for example) to guarantee that if you allocate a chunk which is smaller than or equal to 64 kilobytes, the extent of the buffer you receive will not cross a 64K boundary. 可能造成不满足4K对齐的原因如下: 用户内核PAGESIZE小于4096字节 dma_alloc_coherent实现方式与Linux社区...
Linux: $sudokill-SIGUSR1$(pidof dockerd) Windows Server: Downloaddocker-signal. Get the process ID of dockerdGet-Process dockerd. Run the executable with the flag--pid=<PID of daemon>. This forces a stack trace to be logged but doesn't stop the daemon. Daemon logs show the stack trace...
One notable example of a configuration conflict that's difficult to troubleshoot is when you want to specify a different daemon address from the default. Docker listens on a socket by default. On Debian and Ubuntu systems usingsystemd, this means that a host flag-His always used when starting...
假设你拿到了一个linux系统,里面有一个文件,不过没有可执行权限,但是你必须要执行它,你会怎么办?聪明的你肯定会毫不犹豫的回答:chmod +x,恭喜你答对了。但是你有没有想过 chmod 文件本身如果也没有可执行权限,你该怎样做? 如何给chmod 文件添加可执行权限呢? 这就是CTF(Capture The Flag)的魅力 ～ ailx10...
As described inkernel commit 643f81115baca3630e544f6874567648b605efaesome NFS servers end their READDIR or READDIRPLUS directories listings with and empty list without setting the EOF flag (cf RFC1813 section 3.3.16 for READDIR description). The Linux kernel consider this as a problem on the ...
-n --nmagic Turn off page alignment of sections, and mark the output as "NMAGIC" if possible. -N --omagic Set the text and data sections to be readable and writable. Also, do not page-align the data segment, and disable linking against shared libraries. If the output format supports...
L6065E:Load region <name> (size <size>) is larger than maximum writable contiguous block size of 0x80000000. The linker attempted to write a segment larger than 2GB. The size of a segment is limited to 2GB. L6175E:EMPTY region <regname> cannot have any section selectors. L6176E:A...
Nonetheless, if-vvor above is necessary for monitoring purposes, add one of the following options to the actual command. Solution 1 - Disableinc-recursivemode Add--no-inc-recursiveflag to the current options: Raw $ rsync -avv --no-inc-recursive /src/ /dst/ ...
To build an image for the amd64 platform, use the --platform flag. $ docker build --platform linux/amd64 -t YOUR-USER-NAME/getting-started . Docker buildx also supports building multi-platform images. To learn more, see Multi-platform images. ...
