  - ext4內嵌修正 ext4_prepare_inline_data 中的 len 溢位。在已啟用 inline_data 功能的 ext4 檔案系統上執行下列程式碼時會導致下列錯誤。 fd = open(file1, O_RDWR | O_CREAT | O_TRUNC, 0666) ftruncate(fd, 30); pwrite(fd, a, 1, (1UL << 40) + 5UL);會發生這種情況是因為 write_begin 會在 ext4_generic_write_inline_data 呼叫 ext4_prepare_inline_data 時成功執行 pos + len 會遭到截斷進而導致 ext4_prepare_inline_data 參數為 6 而非 0x10000000006。之後當呼叫 write_end 時我們會命中 BUG_ON(pos + len > EXT4_I(inode)->i_inline_size)位於 ext4_write_inline_data。透過針對 ext4_prepare_inline_data 中的 len 參數使用 loff_t 類型而非未簽署的 int 來修正此問題。 [ 44.545164] ------------[剪到這裡]------------ [ 44.545530] fs/ext4/inline.c:240! 的核心錯誤[ 44.545834] Oops無效 opcode0000 [#1] SMP NOPTI [ 44.546172] CPU3 UID 0 PID 343 Commtest 未受污染的 6.15.0-rc2-00003-g9080916f4863 #45 PREEMPT(完整) 112853fcebfdb93254270a7959841bbcaa62bcaa8 [ 44.546523] 硬體名稱QEMU Standard PC (i440FX + PIIX, 1996)BIOS 1.16.3-debian-1.16.3-2 04/01/2014 [ 44.546523] RIP 0010:ext4_write_inline_data+0xfe/0x100 [44.546523] 程式碼3c 0e 48 83 c7 48 48 89 de 5b 41 5c 41 5d 41 5e 41 5f 5d e9 e4 fa 43 01 5b 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc cc 0f 0b <0f> 0b 0f 1f 44 00 00 55 41 57 41 56 41 55 41 54 53 48 83 ec 20 49 [44.546523] RSP0018:ffffb342008b79a8 EFLAGS00010216 [ 44.546523] RAX 0000000000000001 RBX
